Epoprostenol is metabolized to 2 primary metabolites: 6-keto-PGF1α (formed by spontaneous degradation) and 6,15-diketo-13,14-dihydro-PGF1α (enzymatically formed), both of which have pharmacological activity orders of magnitude less than epoprostenol in animal test systems. Fourteen additional minor metabolites have been isolated from urine, indicating that epoprostenol is extensively metabolized in humans.

Small molecule calpain modulator compounds, including their pharmaceutically acceptable salts, can be included in pharmaceutical compositions. The compounds can be useful in inhibiting calpain, or competitive binding with calpastatin, by contacting them with CAPN1, CAPN2, and/or CAPN9 enzymes residing inside a subject. The compounds and composition can also be administered to a subject in order to treat a fibrotic disease or a secondary disease state or condition of a fibrotic disease.

Disclosed is an improved method of synthesis for Treprostinil comprising condensation reaction of compound (4) with a hydroxyl-protected alkynol (5) to give the condensation product, compound (6). Subjecting compound (6) to oxidation, reduction, hydroxyl protection and carbonylation, cyclization reactions gives the tricyclic derivative (10). Further reactions comprising reduction, hydrogenation and deprotection of the phenolic and side-chain hydroxyl groups, wherein the sequence and choice of reagents is governed by protecting groups, give the triol intermediate, compound (14). Cyanoalkylation at phenolic hydroxyl functionality and further hydrolysis yields the prostacyclin compound, Treprostinil (1) and its pharmaceutically acceptable salts with desired purity.
