Abstract:

In this work, the title compound was synthesized via the visible-light-induced radical denitrogenative trifluoromethylation of the corresponding vinyl azide followed by Cs2CO3-mediated defluorinative cyclization of the resultant azine. The widely available sodium trifluoromethanesulfinate is used as a precursor of CF3 radicals, while graphitic carbon nitride (g-C3N4) is employed as an environmentally friendly, cheap, and efficient heterogeneous photocatalyst. The structure of the synthesized compound was established by 1H, 13C, 19F-NMR, IR spectroscopy, and mass-spectrometry.

Abstract:

3-Amino-4-morpholino-1H-indazol-1-yl(3-fluorophenyl)methanone was synthesised by condensation of 3-fluorobenzoic acid with 4-morpholino-1H-indazol-3-amine, which was prepared from 2,6-difluorobenzonitrile by amination with morpholine and then cyclisation with hydrazine hydrate. The molecular structure was tested by single crystal X-ray diffraction. Preliminary biological tests showed that the compound possesses distinct inhibition on the proliferation of A549, BGC-823 and HepG-2 cancer cell lines.

Abstract:

A new series of N-benzylindolylchalcone analogs has been designed, synthesized, and screened for in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv. The synthesis of N-benzylatedindole-3-carbaldehyde derivatives, namely, -1-(2-methylbenzyl)-1H-indole-3-carbaldehyde (S2I1)1-(3-methylbenzyl)-1Hindole-3-carbaldehyde (S2I2), was achieved by N-benzylation of indole-3-carbaldehyde using a mixture of different bases in DMF. Subsequent condensation of these derivatives with various acetophenones led to the synthesis of the corresponding N-benzylindolylchalcone derivatives. Notab

Abstract:

The green analytical HPLC methods are highly effective for quantifying drugs because these methods reduce the usage of harmful chemicals and generate less waste leading to minimal environmental influence. Various compositions of green solvents including ethanol and water with buffers were utilized as mobile phase. The conditions that produce acceptable results were studied for valuation in terms of linearity, accuracy, precision and sensitivity. This method was applied for the sepration and characterization of degradation products (DPs) of ripretinib using LCMS/MS. The method comprises of Asce

Abstract:

In the title compound, C20H19FN6S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The dihedral angle between the least-squares plane through the pyrazole and triazole rings is 7.59 (9)°, and the triazole and attached benzene ring form a dihedral angle of 74.79 (9)°. The thiourea group is coplanar with the pyrazole ring [N—N—C—S torsion angle = −179.93 (11)°], which enables the formation of an intramolecular N—H...N hydrogen bond. In the crystal, inversion-related molecules associate via N—H...S hydrogen bonds and eight-membered {...HNCS}2 synthons
