Since α,β-unsaturated compounds are electrophiles and alkylating agents, many α,β-unsaturated carbonyl compounds are toxic. The endogenous scavenger compound glutathione naturally protects from toxic electrophiles in the body. Some drugs (amifostine, N-acetylcysteine) containing thiol groups may protect from such harmful alkylation.
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
Many electrophiles are chiral and optically stable. Typically chiral electrophiles are also optically pure. One such reagent is the fructose-derived organocatalyst used in the Shi epoxidation. [11] The catalyst can accomplish highly enantioselective epoxidations of trans-disubstituted and trisubstituted alkenes.
Clomifene successfully induced ovulation in subfertile women and on February 1, 1967, it was approved in the US for the treatment of ovulation dysfunction in women who were trying to conceive. [5] Toxicological issues prevented long term use of clomifene and further drug development for other potential applications such as breast cancer ...
This is a list of 5α-reductase inhibitors (5α-RIs), drugs which inhibit one or more isoforms of the enzyme 5α-reductase.This enzyme is responsible for the conversion of the androgen hormone testosterone into the more potent dihydrotestosterone (DHT) and is essential for the production of neurosteroids like allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), and 3α-androstanediol from ...
Compared with certain other L-type calcium channel blockers (for example those of the phenylalkylamine class such as verapamil) that have significant action at the heart, the dihydropyridine calcium channel blockers lower blood pressure mainly by relaxing the smooth muscle of the blood vessel walls.

"In the 60s, the skin tends to become drier, thinner and more delicate due to decreased natural oil production and a decline in collagen and elastin," said Dr. Hannah Kopelman, host of the podcast ...
Studies have evaluated the effect of herbal anaphrodisiacs on men and women. These include studies on the effect of substances on both hormone levels and behaviour. The mechanism of the active component of some plant-based anaphrodisiacs may be the inhibition of enzymes that catalyze the conversion of sex-hormone precursors into androstenedione ...
