In a search for new 1, 4-dihydropyridine derivatives with a long-lasting effect on the cardiovascular system, a series of piperazinylalkyl esters (I) bearing a lipophilic substituent on the 4-nitrogen of the piperazine ring was synthesized and tested for hypotensive effect in spontaneously hypertensive rats (SHR). Compounds I, especially those having a diphenylmethyl moiety on the piperazine ring, showed extremely potent and long-lasting hypotensive properties. Analogues related to I were also prepared, and the structure-activity relationships are discussed.

The described invention provides a biodegradable, biocompatible delivery system of flowable sustained release microparticulate composition of a substantially pure crystalline form of a bioactive agent such as, for example, nimodipine, a process of preparing a therapeutic form of a substantially pure crystalline form of the bioactive agent and a method for treating an interruption of a cerebral artery in a subarachnoid space at risk of interruption caused by brain injury in a mammal, which reduces signs or symptoms of at least one delayed complication associated with brain injury.

approximately three-fold more active than nifedipine as a calcium antagonist. A docking study with the DHP receptor model was performed to interpret the differences in calcium antagonist activities. The molecular docking study demonstrated that the lipophilicity of the substituted phenyl group at the 4-position of the DHP ring is an important factor that could increase the activity of the calcium antagonist
