Pregnanolone - Wikipedia
Pregnanolone, also known as eltanolone (INN), is an endogenous neurosteroid that is biosynthesized from progesterone. It is a positive allosteric modulator of the GABAA receptor, as well as a negative allosteric modulator of the glycine receptor, and is known to have sedative, anxiolytic, anesthetic, and anticonvulsant effects. It was investigated for clinical use as a general anesthetic, but produced unwanted side effects such as convulsions on occasion, and for this reason was never marketed. During pregnancy, pregnanolone and allopregnanolone are involved in sedation and anesthesia of the fetus. ...https://en.wikipedia.org/wiki/Eltanolone
Ciprofloxacin - Wikipedia
Ciprofloxacin is used to treat a wide variety of infections, including infections of bones and joints, endocarditis, gastroenteritis, malignant otitis externa, respiratory tract infections, cellulitis, urinary tract infections, prostatitis, anthrax, and chancroid.. Ciprofloxacin only treats bacterial infections; it does not treat viral infections such as the common cold. For certain uses including acute sinusitis, lower respiratory tract infections and uncomplicated gonorrhea, ciprofloxacin is not considered a first-line agent.. Ciprofloxacin occupies an important role in treatment guidelines issued by major medical societies for the treatment of serious infections, especially those likely to be caused by Gram-negative bacteria, including Pseudomonas aeruginosa. For example, ciprofloxacin in combination with metronidazole is one of several first-line antibiotic regimens recommended by the Infectious Diseases Society of America for the treatment of community-acquired abdominal infections in ...https://en.wikipedia.org/wiki/Cipro
5α-Dihydroprogesterone - Wikipedia
5α-Dihydroprogesterone (5α-DHP), also known as allopregnanedione, as well as 5α-pregnane-3,20-dione, is an endogenous progestogen and neurosteroid that is synthesized from progesterone. It is also an intermediate in the synthesis of allopregnanolone and isopregnanolone from progesterone. 5α-DHP is an agonist of the progesterone receptor and a positive allosteric modulator of the GABAA receptor (albeit with an affinity for this receptor that is regarded as relatively low (in comparison to 3α-hydroxylated progesterone metabolites such as allopregnanolone and pregnanolone)). It has also been found to act as a negative allosteric modulator of the GABAA-rho receptor. In addition, it is a weak agonist of the pregnane X receptor (PXR) (EC50 ,10,000 µM)), with approximately six-fold lower potency relative to its 5β-isomer, 5β-dihydroprogesterone.. ...https://en.wikipedia.org/wiki/5-alpha-dihydroprogesterone
