Enantiomers of β-lactams bearing aryl, furyl or styryl substituents in the 4-position were chromatographically separated by means of high-performance liquid chromatography on chiral column packed with amino acid-derived chiral stationary phase. Sepa

Several 7α-thiosubstituted derivatives of androstenedione have demonstrated effective inhibition of aromatase, the cytochrome P450 enzyme complex responsible for the biosynthesis of estrogens. Introduction of an additional double bond in the A ring

Enantioselective synthesis of optically active β-lactam via ester enolate-imine condensation using homochiral ester 16 and imine 17 provided β-lactam 18a in 77% cc. Lactam 18a, carried C(3) functionality on β-lactam nuclei, provided a potential pr

Effective aromatase inhibitors have been developed that contain aryl functionalities at the 7 alpha-position of the steroid nucleus. The exact interactions of 7 alpha-substituted androstenediones with the active site of aromatase is unknown. Fluoresc

Androstenedione analogs containing 7 alpha-substituents have proven to be potent inhibitors of aromatase both in vitro and in vivo. Several of these agents have exhibited higher affinity for the enzyme complex than the substrate. In order to examine

Es wird die Darstellung einiger kondensierter Perimidin-Derivate und ihre Prufung auf anorektische Wirkung beschrieben. Die wirksamste Substanz 4c zeigte keine ZNS-Wirkung und dies weist darauf hin, das diese Derivate einen anderen anorektischen Wirk

Refluxing 2-hydrazinoperimidine (1) with excess amount of diethyl oxalate (2a) gave ethyl 1H-1,2,4-triazolo[4,3-a]perimidine-3-carboxylate (4a) in 84% yield. On the other hand, heating 1 with ethyl pyruvate (2b) in glacial acetic acid afforded 3-meth
