This molecule features a five-membered ring (C1-N2-C3-N4-C5) containing one sp3-hybridized carbon at position 1. The sp3 carbon, which has an R configuration, is bonded to a phenyl ring and an ethyl. N2 is double-bonded to C3, and C3 bears a hydroxyl substituent. C5 is double-bonded to an oxygen atom.
N4 is further substituted by a two-carbon chain. The second carbon of this chain carries a hydroxyl group and is double-bonded to a nitrogen forming an imine. This imine nitrogen is connected to the second stereogenic center (S configuration). This second chiral carbon is attached to (i) a five-membered thiophene ring at the adjacent position of the sulfur, and (ii) a phenyl ring bearing a methyl substituent at the para position.
