Therefore, it is likely that the pharmacophoric descriptors in arylsemicarbazones are thought to be a hydrogen bonding semicarbazone group and a lipophilic aryl ring which align at their complementary areas on the macromolecular complex in vivo [23].
Dihydro-LH-imidazo [1,5-b]pyrazole-4,6(2H,5H)-dione 119 was synthesized from treatment 1-(benzylideneamino)-5-(2-hydroxyethyl)hydantoin 117, prepared from treated sodium salt of acetone semicarbazone 115 with a-bromo-y-butyrolactone 116 and the reaction mixture was then subjected to acid hydrolysis followed by condensation with benzaldehyde, with SO[Cl.sub.2] to give 1-benzylidene-2,3,3a,4,5,6-hexahydro-4,6-dioxo-1H-imidazo[1,5-b]pyrazolium chloride 118.
