Could someone clarify the patent status of Targretin?

 

http://www.drugs.com...gretin-gel.html

 

If there is a generic version as noted below, why are there posts about $49,000 Bexarotene annual treatment costs?

A generic drug should be priced, theoretically,  at marginal cost which is much much closer to $0 than it is to $49,000.

 

This is of considerable relevance here as the AD patient who was on Bexarotene and stabilized for 2 years had to give up treatment due to

the 1,200 euro per month expense. If we are now talking about $20 copay prescriptions, then money limitations are now off the table.

 

Is a generic drug company typically (aside from some notable recent examples) truly allowed to charge pharmaceutical

scale prices for a drug in which they have not been exposed to any development risk? In this instance there is some mention

of generic exclusivity of Targretin for a particular company.

 

 

http://www.empr.com/...article/425463/

 

There is also mention of an October 2016 patent expiration for Targretin.

Should this be the date when large price declines should be expected?

 

I suppose there might be quite a few more prescriptions for the "cancer" indication with the $20 copay.

Inflammatory mediators leading to protein misfolding and uncompetitive/fast off-rate drug therapy for neurodegenerative disorders.

Inflammatory mediators, including free radicals such as nitric oxide (NO) and reactive oxygen species (ROS), can contribute to neurodegenerative diseases in part by triggering protein misfolding. In this chapter, we will discuss a newly discovered pathway for this phenomenon and possible novel treatments. Excitotoxicity, defined as overstimulation of glutamate receptors, has been implicated in a final common pathway contributing to neuronal injury and death in a wide range of acute and chronic neurological disorders, ranging from Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), multiple sclerosis, and Alzheimer's disease (AD) to stroke and trauma. Excitotoxic cell death is due, at least in part, to excessive activation of N-methyl-d-aspartate (NMDA)-type glutamate receptors, leading to excessive Ca(2+) influx through the receptor's associated ion channel and subsequent free radical production, including NO and ROS. These free radicals can trigger a variety of injurious pathways, but newly discovered evidence suggests that some proteins are S-nitrosylated (transfer of NO to a critical thiol group), and this reaction can mimic the effect of rare genetic mutations. This posttranslational modification can contribute to protein misfolding, triggering neurodegenerative diseases. One such molecule affected is protein disulfide isomerase (PDI), an enzyme responsible for normal protein folding in the endoplasmic reticulum (ER). We found that when PDI is S-nitrosylation (forming SNO-PDI), the function of the enzyme is compromised, leading to misfolded proteins and contributing to neuronal cell injury and loss. Moreover, SNO-PDI occurs at pathological levels in several human diseases, including AD and PD. This discovery thus links protein misfolding to excitotoxicity and free radical formation in a number of neurodegenerative disorders. Another molecule whose S-nitrosylation can lead to abnormal protein accumulation is the E3 ubiquitin ligase, parkin, which contributes to the pathogenesis of PD. One way to ameliorate excessive NO production and hence abnormal S-nitrosylations would be to inhibit NMDA receptors. In fact, blockade of excessive NMDA receptor activity can in large measure protect neurons from this type of injury and death. However, inhibition of the NMDA receptor by high-affinity antagonists also blocks the receptor's normal function in synaptic transmission and leads to unacceptable side effects. For this reason, many NMDA receptor antagonists have disappointingly failed in advanced clinical trials. Our group was the first to demonstrate that gentle blockade of NMDA receptors by memantine, via a mechanism of uncompetitive open-channel block with a rapid "off-rate," can prevent this type of damage in a clinically efficacious manner without substantial side effects. For these Uncompetitive/Fast Off-rate therapeutics, we use the term "UFO drugs" because like Unidentified Flying Objects, they leave very quickly as soon as their job is finished. As a result, memantine blocks excessive NMDA receptor activity without disrupting normal activity. Memantine does this by preferentially entering the receptor-associated ion channel when it is excessively open, and, most importantly, when its off-rate from the channel is relatively fast so that it does not accumulate to interfere with normal synaptic transmission. Hence, memantine is clinically well tolerated, has been used in Europe for PD for many years, and recently passed multiple phase III trials for dementia, leading to its approval by the FDA and European Union for moderate-to-severe AD. Clinical studies of memantine for additional neurological disorders, including other dementias, neuropathic pain, and glaucoma, are underway. We have also developed a series of second-generation drugs that display greater neuroprotective properties than memantine. These second-generation drugs take advantage of the fact that the NMDA receptor has other modulatory sites, including critical thiol groups that are S-nitrosylated. In this case, in contrast to PDI or parkin, S-nitrosylation proves to be neuroprotective by decreasing excessive NMDA receptor activity. Targeted S-nitrosylation of the NMDA receptor can be achieved by coupling NO to memantine, yielding second-generation "UFO drugs" known as NitroMemantines.

A recent paper of a discovery about the similarity of laminopathies and age-related progressive neurodegenerative disorders:

Lamin Dysfunction Mediates Neurodegeneration in Tauopathies
Frost B, Bardai FH, Feany MB
Curr Biol. 2016 Jan 11
http://www.ncbi.nlm....pubmed/26725200
Abstract
The filamentous meshwork formed by the lamin nucleoskeleton provides a scaffold for the anchoring of highly condensed heterochromatic DNA to the nuclear envelope, thereby establishing the three-dimensional architecture of the genome [1]. Insight into the importance of lamins to cellular viability can be gleaned from laminopathies, severe disorders caused by mutations in genes encoding lamins. A cellular consequence of lamin dysfunction in laminopathies is relaxation of heterochromatic DNA [1]. Similarly, we have recently reported the widespread relaxation of heterochromatin in tauopathies [1]: age-related progressive neurodegenerative disorders, including Alzheimer's disease, that are pathologically characterized by aggregates of phosphorylated tau protein in the brain [2, 3]. Here we demonstrate that acquired lamin misregulation though aberrant cytoskeletal-nucleoskeletal coupling promotes relaxation of heterochromatin and neuronal death in an in vivo model of neurodegenerative tauopathy. Genetic manipulation of lamin function significantly modifies neurodegeneration in vivo, demonstrating that lamin pathology plays a causal role in tau-mediated neurotoxicity. We show that lamin dysfunction is conserved in human tauopathy, as super-resolution microscopy reveals a significantly disrupted nuclear lamina in postmortem tissue from human Alzheimer's disease brain. Our study provides strong evidence that tauopathies are neurodegenerative laminopathies and identifies a new pathway mediating neuronal death in currently untreatable human neurodegenerative disorders, including Alzheimer's disease.

 
Interesting... but do you have any clue what to do to prevent this? Would HDAC inhibitors help to keep the DNA archored to the nuclear envelope, by virtue of not unfurling so readily?

I am not sure yet, because this is rather new:

as the corresponding entry in the blog of the current university of the study's main author writes:
Skeleton That Protects Brain Cells’ Control Center Is Found To Be Damaged
http://gsbs.uthscsa....d-to-be-damaged
"... Dr. Frost and two co-authors showed - for the first time - that lamin dysfunction can cause the death of brain cells, which are called neurons. ..."

Fungal infection of AD brain [5, 6] has also been described, as well as abnormal microbiota in AD patient blood. The first observations of HSV1 in AD brain were reported almost three decades ago].

It is especially disappointing that evidence exists for a dementia connection to herpes simplex 1.

If HSV-1 were causing the epidemic of this century, would not a focused global effort be capable of developing a vaccine for it?

At least then we would not have decades more debate about whether or not herpes is causing Alzheimer's!

 

In fact the infectious hypothesis crops up time and time again in the research literature.

Various diseases might or might not be related to infections.

 

Should it not be a Global Millennial goal that all such infectious agents which might cause illness should be targeted for significant

financing? The world is already spending well over $1 billion per day on dementia. Investing in vaccines would make a very

good investment.

 

A herpes vaccine would surely be a great place to start, though from wiki:

 

"... has failed to proceed to a Phase III trial in the year 2006, due to financial reasons."

or "...  Although already proven as very safe and effective in studies on animals, [a proposed herpes]  vaccine is currently not involved in any clinical trials,

Can we really afford not to fund these vaccines?

Resveratrol synergises with vit D to increase vitamin D receptors (VDR) and cathelicidin antimicrobial peptide (CAMP) IIRC.

Now the less pure extracts of R are from Japanese Knotweed, which is high in Emodin...

 

NB that Pterostilbene is basically a more bioavailable form of Resveratrol.

ie: Pt is likely to give the in vitro effects R, while the metabolites of R are what you should be researching if you want the learn about it's effects  in vivo.

 

Pt also disrupts biofilms like that formed by Candida.

Metiformin and other AMPK activators are not looking too good.

 

http://www.ncbi.nlm....pubmed/26967226

 

 

The evidence of strong pathological associations between type 2 diabetes and Alzheimer's disease (AD) has increased in recent years. Contrary to suggestions that anti-diabetes drugs may have potential for treating AD, we demonstrate here that the insulin sensitizing anti-diabetes drug metformin (Glucophage®) increased the generation of amyloid-β (Aβ), one of the major pathological hallmarks of AD, by promoting β- and γ-secretase-mediated cleavage of amyloid-β protein precursor (AβPP) in SH-SY5Y cells. In addition, we show that metformin caused autophagosome accumulation in Tg6799 AD model mice. Extremely high γ-secretase activity was also detected in autophagic vacuoles, apparently a novel site of Aβ peptide generation. Together, these data suggest that metformin-induced accumulation of autophagosomes resulted in increased γ-secretase activity and Aβ generation. Additional experiments indicated that metformin increased phosphorylation of AMP-activated protein kinase, which activates autophagy by suppressing mammalian target of rapamycin (mTOR). The suppression of mTOR then induces the abnormal accumulation of autophagosomes. We conclude that metformin, an anti-diabetes drug, may exacerbate AD pathogenesis by promoting amyloidogenic AβPP processing in autophagosomes.

 

 

Note: bold-face added by me.

 

http://www.ncbi.nlm....pubmed/21623793

 

 

... However, the responses of AMPK activation are dependent on stimulation and the extent of activating stress. Evidently, AMPK signaling can repress and delay the appearance of AD pathology but later on, with increasing neuronal stress, it can trigger detrimental effects that augment AD pathogenesis. We will outline the potential role of AMPK function in respect to various aspects affecting AD pathogenesis.

Emodin has potent anti-herpes activity.

Expanding on two (1, 2) previous posts on the general antiviral actions on Emodin, it also seems to be very effective for Herpes Simplex 1. What I find interesting though, is that it's capable of actually reducing the viral load in the brain and other organs. Given the recent association of neurodegenerative diseases and Herpes infections, I think this could have some important applications. Most substances that kill the herpes virus are virucidal only against the free virus. That is, they don't affect the total viral burden inside the cell. Only the extracellular virions are affected and this makes them great topical agents. If you want to eradicate the virus completely (*cough, cure ?) you need to reduce the viral load inside the cells. I thought this was impossible but I found a few substances that can do this. Emodin is one.

Some good BHT info here:

http://www.longecity...opic/42592-bht/

[niner]

Well, let's look at the record.  Emodin does have some moderate anti-herpes activity, but only at huge doses that would cause massive diarrhea in humans, and this was only shown in mice which show much better response to polyphenols than humans.  So there's no evidence that it would work in humans.  The authors of this paper made the odd claim that "the antiviral activity of emodin was found to be equivalent to that of acyclovir in vivo", although the typical dose of acyclovir is much lower than the doses of emodin they used, even adjusting for interspecies scaling.  Maybe acyclovir doesn't work well in mice? 
 
BHT looks a little scary as an oral drug:
 
http://www.ncbi.nlm....les/PMC1010948/
http://www.ncbi.nlm..../pubmed/4045049
http://www.ncbi.nlm....les/PMC1306899/
.
As a topical drug dissolved in oil, it showed some improvement in healing of genital herpes sores. This is a reasonable use of BHT, but it's not clear that it's any better than existing treatments, and isn't a cure, but does sound like it would make you feel better a little sooner.

 

VCO seems to be considered antimicrobial because monolaurin is derived from it, and monolaurin has been shown to have antimicrobial properties.  However, you don't get enough monolaurin from VCO in vivo to have an antimicrobial effect.  Here is a paper that looked at both monolaurin and VCO in vivo against S. Aureus; the monolaurin worked, VCO had no effect.

 

VCO may be helpful for Alzheimers patients, possibly through the formation of ketone bodies, but I seriously doubt that the mechanism is antimicrobial.
 

So I stand by my "nopes" on these three substances as herpes eradication tools.  At present, I don't think there is anything that can truly eradicate herpes because it is so good at hiding out in neurons.  The possible anti-herpetic action of emodin is likely not enough to compensate for its bad PK and toxicity.  BHT might be useful topically.  VCO tastes great.  I have it on oatmeal all the time.

 

Since this is an AD thread, I'll mention that the connection between HSV and AD is not entirely clear; it might be a risk factor, but isn't "the" cause.

Nanoscopic insights into seeding mechanisms and toxicity of α-synuclein species in neurons

The self-assembly of normally soluble proteins into fibrillar amyloid structures is associated with a range of neurodegenerative disorders. Here, we monitor the fate of different forms of α-synuclein (AS), a protein implicated in Parkinson’s disease, via optical nanoscopy directly in neuronal cells. We show that exogenously added preformed AS fibrils elongate by the addition of endogenous AS, naturally present in neurons. In contrast, exogenously added monomeric AS induces aggregate formation within the cells and leads to apoptosis. The latter is significantly reduced by the addition of preformed fibrils, suggesting a neuroprotective role of fibrillar species. The visualization of these effects at the nanoscale shown here opens up new avenues for understanding the links between AS aggregation and neuronal toxicity.
