Rapamycin: Anti-aging and metabolic dream drug?
-
I will tag you, but this question can be addressed to anyone here who is taking this “Wonder drug“
How do you reconcile that this is big Pharma:
Pfizer and Wyeth?Red flags personally for me as well as it’s catching on mainstream

Of course I think it has therapeutic benefits, but I would isolate those to compromised kidney patients, etc.

Rapamycin might help schizophrenia by lowering mTOR.
Schizophrenics have increased 5ht6 activation which in turn activates mTOR.
"Further, 5-HT(6) receptor activation increased mTOR signalling in rodent prefrontal cortex (PFC). Linking this signalling event to cognitive impairment, the mTOR inhibitor rapamycin prevented deficits in social cognition and novel object discrimination induced by 5-HT(6) agonists. In two developmental models of schizophrenia, specifically neonatal phencyclidine treatment and post-weaning isolation rearing, the activity of mTOR was enhanced in the PFC, and rapamycin, like 5-HT(6) antagonists, reversed these cognitive deficits. These observations suggest that recruitment of mTOR by prefrontal 5-HT(6) receptors contributes to the perturbed cognition in schizophrenia, offering new vistas for its therapeutic control."

Rapamycin, fisetin and other anti-aging compounds (but not Metformin) help with stem cell formation .
-
Another macrolide antibiotic Azithromycin also inhibits mTOR according to these studies:

Azithromycin might have interesting anti-aging effects. It targets senescent cells very effectively and without targeting healthy cells. The effect is concentration dependant though .
"Azithromycin preferentially targets senescent cells, removing approximately 97% of them with great efficiency. This represents a near 25-fold reduction in senescent cells."
"Azithromycin, at 100 μM, had no effect on the viability of normal MRC-5 lung fibroblasts, but selectively killed only senescent MCR-5 fibroblasts."
"Neither drug showed any significant effects on viability at 50 μM, indicating that the effects we observed were concentration-dependent."

@Mauritio I took approx 40 mg azithromycin plus .5g of cypro daily for about 3 weeks during allergy season, and I seemed to do better than with just cypro.
I've wondered if there would be any negative effects from longterm lowdose usage, like Peat's concern that using too much of one antibiotic causing imbalance in the microbiome.
-
@LetTheRedeemed interesting . Did you notice any other effects from it ?
-
@Mauritio I couldn't connect if I was having digestive issues connected to it's prolonged use or not. there were a lot of confounders at the time. I'll probably try it again next time I use it with some penicillin traveling el snail mail.

I’ve not been that impressed with rapamycin personally, as it gives me a headache and interferes with sleep.
But low dose naltrexone and deprenyl are quite amazing and are great longevity drugs. LDN in particular has made a huge different for so many people as it can seal leaky gut — which is the source of virtually all chronic disease as we age.
-
@Ecstatic_Hamster say no more, where does one get LDN?
-
@Ecstatic_Hamster I've been wanting to try LDN for a long time . Is there anywhere we can read about people's experience with it ?

@Mauritio said in Rapamycin: Anti-aging and metabolic dream drug?:
Surprisingly this review argued that quinones would increase mTOR.
Because quinones increase Nrf2 which in turn increases mTOR.What should we think of that ?
In theory that would cause a pro-cancer effect, but quinones do lot more than activating Nrf2 ...Here's a few studies that a quinone, thymoquinine to be precise, inhibits mTOR and thus has an anti-cancer effect.
