cifenline · cibenzoline succinate · cifenline succinate
Cibenzoline (or cifenline) is a Class Ia antiarrhythmic. Pituxate & Ecipramidil are other gem-diphenyl cyclopropanyl drugs.
Adaprolol is a beta blocker.
Prorenone (developmental code name SC-23133) is a steroidal antimineralocorticoid of the spirolactone group related to spironolactone that was never marketed. It is the lactonic form of prorenoic acid (prorenoate), and prorenoate potassium (SC-23992), the potassium salt of prorenoic acid, also exists. Prorenoate potassium is about 8 times more potent than spironolactone as an antimineralocorticoid in animals, and it may act as a prodrug to prorenone.
Abitesartan (INN) is an Angiotensin II receptor antagonist.
6 beta, 7 beta, 15 beta, 16 beta-dimethylene-1,4-androstadiene-(17(beta-1')-spiro-5')-perhydrofuran-2',3-dione
Spirorenone (INN) (developmental code name ZK-35973) is a steroidal antimineralocorticoid of the spirolactone group that was never marketed. Spirorenone possesses 5–8 times the antimineralocorticoid activity of spironolactone in animal studies. The initial discovery of spirorenone was deemed a great success, as no compound with greater antimineralocorticoid activity had been developed since spironolactone in 1957.
