Elgaafary, Menna;Lehner, Julia;Fouda, Ahmed M.;Hamed, Abdelaaty;Ulrich, Judith;Simmet, Thomas;Syrovets, Tatiana;El-Agrody, Ahmed M. research published 《 Synthesis and evaluation of antitumor activity of 9-methoxy-1H-benzo[f]chromene derivatives》, the research content is summarized as follows. Herein, a series of aryl-substituted derivatives of 3-amino-1-aryl-9-methoxy-1H-benzo[f]chromene-2-carbonitriles (4a-4q) were designed and synthesized via reaction of 7-methoxy-2-naphthol with a mixture of appropriate aromatic aldehydes and malononitrile under microwave conditions. Among the tested benzochromene, the known compound 4e and four novel compounds 4f, 4j, 4k, 4m exhibited the highest cytotoxicity towards a panel of six human cancer cell lines MDA-MB-231, A549, HeLa, MIA PaCa-2, RPMI 7951, and PC-3. Compound 4j with 2,4-dichloro substitution on the pendant Ph ring exhibited the highest broad-spectrum cytotoxicity towards all tested cancer cell lines. Compounds 4e, 4f, 4j, 4k, 4m were further selected to study the mechanism of cellular toxicity using the triple-neg. breast cancer cells MDA-MB-231. Compounds 4e, 4f, 4j, 4k, 4m induced accumulation of the treated MDA-MB-231 cells in the S phase and 4k addnl. in the G2/M phase of the cell cycle. Compounds 4e, 4f, 4j, 4k, 4m induced dissipation of mitochondrial transmembrane potential and activation of caspase 3/7 in MDA-MB-231 cells with 4j being one of the most active. In an in vivo model, compound 4j and less efficiently 4e and 4f inhibited growth and proliferation and triggered DNA fragmentation in MDA-MB-231 xenografts grown on chick chorioallantoic membranes. SAR study confirmed that the 2,4-dichloro substitution pattern on the pendant Ph ring enhanced the cytotoxic activity of benzochromene.
Electric Literature of 6334-18-5, 2,3-Dichlorobenzaldehyde(2,3-DBA)is a useful research compound. Its molecular formula is C7H4Cl2O and its molecular weight is 175.01 g/mol. The purity is usually 95%.
2,3-DBA is an organic compound that is used as a synthetic intermediate in the preparation of other chemicals. It is prepared by reacting 2-chloroacetophenone with hydrochloric acid and sodium carbonate in a reaction vessel. The product can be purified through fractional distillation or crystallization. The optical properties of 2,3-DBA are determined by its dipole moment and the substituents attached to the methylene group. Molecular modeling studies have shown that felodipine can bind to 2,3-DBA through its active methylene group. The reaction products between sulfadiazine and 2,3-DBA are pyridinedicarboxylic acid and 3-chlorobenzaldehyde.
2,3-DBA is part of a group of Benzaldehyde (B119740) derivatives that exhibit activity against Mycobacterium tuberculosis, the bacteria responsible for causing tuberculosis in humans. 2,3-DBA is also used as a reagent to synthesize (E)-2-(2-arylhydrazinyl)quinoxalines, compounds that have potent anticancer activity., 6334-18-5.
