Synthesis and biological activities of a novel class of azole-containing antifungal agents

A series of novel 1,2,3,4-tetrahydroisoquinoline derived azoles has been designed and synthesized as antifungal agents which might function as inhibitors of cytochrome P-450 dependent lanosterol 14alpha-demethylase. In vitro tests showed that some of these compounds, especially 5b and 6b, effectively inhibit the growth of several strains of yeasts as well as molds.

CRYSTALLINE FORM OF QUINAPRIL HYDROCHLORIDE AND PROCESS FOR PREPARING THE SAME

A novel crystalline form of quinapril hydrochloride of formula (I). An amorphous form of quinapril hydrochloride substantially free of impurities, specially diketopiperazine compound, and conforming to pharmacopoeial specifications formed from the said novel crystalline form of quinapril hydrochloride of formula (I). The crystalline quinapril hydrochloride is in the form nitroalkane solvate in which the nitroalkane is nitromethane, nitroethane and nitropropane. Each such nitroalkane solvate having particular characteristic X- ray diffraction patterns. A process for preparation of amorphous from of quinapril hydrochloride, substantially free of impurities, specially diketopiperazine compound, and conforming to pharmacopoeial specifications, using the novel crystalline quinapril hydrochloride as an intermediate. The process involves obtaining free base compound of formula (V) by adjusting the pH of a solution of the benzyl ester maleate salt of quinapril of formula (V) between 7.5-8.5 in a mixture of water and an organic solvent; catalytic hydrogenation of this compound (V) in an alcoholic solvent in the presence of concentrated hydrochloric acid or hydrogen chloride dissolved in an alcoholic solvent and in the presence of catalytic amounts of Pd/C to obtain a residue containing formula (I); crystallization of the said residue by evaporating the alcoholic solvent from a nitroalkane solvent to give crystalline quinapril hydrochloride, associated with a solvate of the nitroalkane solvent, and drying the crystalline quinapril hydrochloride nitroalkane solvate at a temperature between 40C and 45C under vacuum to give amorphous quinapril hydrochloride of formula (I).
