BACKGROUND 1,4-Diazepine derivatives are the seven membered, nitrogen containing heterocyclic ring systems possessing a wide range of therapeutic applications. 1,4-Diazepines attracted the attention of chemists and druggists due to their biological and medicinal properties, such as antimicrobial, anti-HIV and anticancer activities. Herein, we report the preparation, crystal structure determined...
The title compound, C(28)H(30)N(4)O(2), synthesized from 4-[1-(4-ethoxy-phen-yl)-5-methyl-1H-1,2,3-triazol-4-yl]diphenyl-meth-an-ol and morpholine, consists of a subsituted triazolyl group and a morpholinyl group that crowd the aliphatic C atom of a diphenyl-methyl unit [C(triaz)-C-N(morph) = 110.1 (1)° and C(phen-yl)-C-C(phen-yl) = 103.9 (1)°]. The morpholine ring adopts a chair conformation.
Screening identified 2-(3-((4,6-dioxo-2-thioxotetrahydropyrimidin-5(2H)-ylidene)methyl)-2,5-dimethyl-1H-pyrrol-1-yl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonitrile as an MDM2-p53 inhibitor (IC50 = 12.3 μM). MDM2-p53 and MDMX-p53 activity was seen for 5-((1-(4-chlorophenyl)-2,5-diphenyl-1H-pyrrol-3-yl)methylene)-2-thioxodihydropyrimidine-4,6(1H,5H)-dione (MDM2 IC50 = 0.11 μM; MDMX IC50 = 4.2...
A series of 2-substituted-4,5-diphenyl imidazoles 1a-j were synthesized by refluxing benzil with different substituted aldehydes in the presence of ammonium acetate and glacial acetic acid. Structures of the synthesized compounds were confirmed on the basis of IR, 1H NMR and mass spectral data. Compounds 1a-j were screened for anthelmintic activity. Test results revealed that compounds showed p...
A new flavonoid, acacetin-7-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranoside (1), together with four known flavonoids, apigenin-7-O-β-D-glucopyranosyl-(1 (2), acacetin (3), acacetin-7-O-β-D-glucuronide (4) and genkwanin-5-O-primveroside (5) were isolated from the leaves of Glyphaea brevis. Their structures elucidated by spectroscopic techniques. The compounds (1 - 5) tested for their antiox...
A series of Azetidinone; 3-chloro-1-{4-[8-(2hydroxy-4-methylphenyl)-6,10-dimethyl-4,12-diphenyl2,4,5,11,12-pentaazatricyclo[7.3.0.0 3,7 ]dodeca-1(9), 3(7), 5,10tetraen-2-yl]phenyl}-4-aryl azetidin-2-one (3a-e) and thiazolidinones; 3-{4-[8-(2-hydroxy-4-methylphenyl)-6,10dimethyl-4,12-diphenyl-2,4,5,11,12pentaazatricyclo[7.3.0.0 3,7 ]dodeca-1(9), 3(7), 5,10-tetraen-2yl]phenyl}-2-aryl-1,3-thiazoli...
3′-methyl-2-oxo-1′,5′-diphenyl-1′,7′-dihydrospiro[indoline-3,4′-pyrazolo[3,4-b]pyridine]-6′-carboxylic acid was synthesized using diverse conditions. The best reaction condition consisted of water as solvent under microwave irradiation, affording product in 76% yield.
In an effort to establish new pyrroles and pyrrolo[2,3-d] pyrimidines with improved antimicrobial activity we report here the synthesis and in vitro microbiological evaluation of a series of pyrrole derivatives. A series of new 2-aminopyrrole-3-carbonitriles (1a-d) were synthesized from the reaction of benzoin, primary aromatic amines and malononitrile, from which a number of pyrrole derivative...
