The benzodiazepines (BZs) are the most widely used hypnotics. The thienobenzodiazepine derivative etizolam, 6-(o-chlorophenyl)-8ethyl-1-methyl-4H-s-triazolo[3,4-c]thieno[2,3-e] [1,4]diazepine, is a comparatively new potent anxiolytic and/or hypnotic [1]. The BZs have been considered largely free of neuro-endocrine effect [2]. However, hyperprolactinemia and galactorrhea have been suggested to b...

Objective: The objective of the study is to synthesize some novel 1,5-benzodiazepine derivatives from chalcones. The structures of the newly synthesized compounds were characterized by elemental analysis, infrared, 1H nuclear magnetic resonance, and mass spectroscopic studies. All titled compounds were screened for their anti-inflammatory activity. Methods: In this study, a series of novel 2-(s...

Signal transduction processes involved in blue light-dependent proton pumping were investigated using guard cell protoplasts from Vicia faba.N-[2-(Methylamino)ethyl]-5-isoquinolinesulfonamide, an inhibitor of cyclic AMP- and cyclic GMP-dependent protein kinases, had no effect. 1-(5-Isoquinolinesulfonyl)-2-methylpiperazine (H-7) and calphostin C, inhibitors of protein kinase C, produced slight i...

THE ASYMMETRIC UNIT OF THE TITLE SALT [SYSTEMATIC NAME: 2-methyl-4-(4-methyl-piperazin-4-ium-1-yl)-10H-thieno[2,3-b][1,5]benzodiazepinium bis-(2,4,6-trinitro-phenolate)], C(17)H(22)N(4)S(2+)·2C(6)H(2)N(3)O(7) (-), consists of a diprotonated olanzapinium cation and two independent picrate anions. In the cation, the piperazine ring adopts a distorted chair conformation and contains a positively c...

In the title compound, C(17)H(16)N(2)O(3), the seven-membered diazepine ring adopts a boat conformation with the hy-droxy-substituted C atom at the prow and fused benzene ring C atoms at the stern. The phenyl substituent occupies an equatorial position. The amino group of the ring system is a hydrogen-bond donor to the oxo O atom of an inversion-related mol-ecule, and the hy-droxy group is a hy...

The synthesis and hypnotic evaluation of a new generation of thiazolo[3,2-a][1,3]diazepine analogs are described. Those compounds exhibit potent in vivo activities as ultra-short acting hypnotics. Background of the Invention Surgical procedures require the administration of several intravenous drugs to ensure hypnosis, analgesia, relaxation and control of visceral reflex responses. The use of i...

In the cation of the title compound, C(7)H(13)N(2) (+)·C(6)H(2)N(3)O(7) (-), the seven-membered 1,4-diazepine ring forms a twist chair conformation. The two o-nitro groups in the anion are twisted by 35.0 (7) and 36.0 (9)° from the benzene ring. In the crystal, N-H⋯O hydrogen bonds between the cation and anion along with weak C-H⋯O hydrogen bonds produce chains along the b axis. C-H⋯O hydrogen ...
