The compound 2-amino-4-0~0-6-acety1-7,8-dihydro-3H,9H-pyrimido[4,5-b]-[1,4]diazepine (pyrimidodiazepine or PDA, for short) is a precursor of the red eye pigments called the drosopterins in Drosophila melanogaster. The precursor of PDA is 2-amino-4oxo-6-(~-erythro-l’,2‘,3’-trihydroxypropyl)-7,8-dihydropteridine triphosphate (dihydroneopterin triphosphate or Hz-NTP). The synthesis of of PDA from ...
The clinical need for novel bronchodilators for the treatment of bronchoconstrictive diseases remains a major medical issue. Modulation of airway smooth muscle (ASM) chloride via GABAA receptor activation to achieve relaxation of precontracted ASM represents a potentially beneficial therapeutic option. Since human ASM GABAA receptors express only the α4- and α5-subunits, there is an opportunity...
in the current study, a magnetic inorganic–organic nanohybrid material (hpa/tpi-fe3o4) was produced and used as an efficient, highly recyclable and eco-friendly catalyst for the one-pot and multicomponent synthesis of 3,4-dihydroquinoxalin-2-amine, diazepine-tetrazole and benzodiazepine-2-carboxamide derivatives with high yields and in a short range of time (20–35 min). the nanohybrid catalyst ...
In this paper, has been described the synthesis of some novel tetrazolodiazepine derivatives starting from piperidin-4ones, with a view to test the novel compounds for various biological activities. The structures of the synthesized compounds have been established by IR, H and C NMR, mass and elemental analysis. Representative compounds have been characterized by COSY, HETCOR and DEPT 135 spect...
The benzo[e]pyrimido-[5,4-b]diazepine-6(11H)-one core was discovered as a novel ERK5 (also known as MAPK7 and BMK1) inhibitor scaffold, previously. Further structure-activity relationship studies of this scaffold led to the discovery of ERK5-IN-1 (26) as the most selective and potent ERK5 inhibitor reported to date. 26 potently inhibits ERK5 biochemically with an IC₅₀ of 0.162 ± 0.006 μM and in...
N-Cyclohexyl-2,4,4-trimethyl-2,3,4,5-tetrahydro-1H-benzo[b][1,5]diazepine-2-carboxamide (5) was synthesized using an efficient, highly recyclable and eco-friendly catalyst heteropolyacid/triethoxysilyl)propyl]isonicotinamide (HPA/TPI-Fe3O4 nanoparticles) in one-pot. The compound 5 was characterized by FT-IR,1H NMR, 13C NMR, mass spectra, and elemental analysis. The theoretical calculations on 5...
