Since clonidine was introduced in clinical practice, attempts are still made to obtain substances capable of centrally controlling blood pressure, however with pharmacological profile better than currently avail- able, such as moxonidine and rilmenidine. Recently synthesized indazole derivatives exert promising action on blood pressure and heart rate in Wistar rats. In the present study, our ai...
To search for novel compounds with potent anti-angiogenic activity, a series of N(1)-(substituted benzyl)-3-(4-methylphenyl)-1H-indazoles (16, 18, 20, 22, 24, 26, 28, 30, 32) and N(2)-(substituted benzyl)-3-(4-methylphenyl)-2H-indazoles (17, 19, 21, 23, 25, 27, 29, 31, and 33) were synthesized. The structures of these regioisomers were established by IR, UV, and NMR spectral data. 3-(4-Methylph...
A small series of tetrahydroindazoles was prepared, starting from 2-acetylcyclohexanone and different hydrazines using reflux and a focused microwave reactor. Microwave irradiation (MW) favored the formation of the desired products with improved yields and shortened reaction times. This is a simple and green method for the synthesis of substituted tetrahydroindazole derivatives. The in vitro an...
A series of indazole N-oxide derivatives have been synthesized and their antichagasic and leishmanocidal properties studied. 3-Cyano-2-(4-iodophenyl)-2H-indazole N1-oxide exhibited interesting antichagasic activity on the two parasitic strains and the two parasitic stages evaluated. Furthermore, besides its trypanocidal activity, 3-cyano-2-(4-nitrophenyl)-2H-indazole N1-oxide showed leishmanoci...
In the title compound, C15H14ClN3O3S, the dihedral angle between the planes of the indazole ring system (r.m.s. deviation = 0.007 Å) and the benzene ring is 89.05 (7)°. The meth-oxy C atom deviates from its attached ring by 0.196 (3) Å. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R 2 (2)(8) loops. The dimers are connected into [010] chains by C-H⋯O inter-ac...
Nitrophenolates (NPs) are molecular anions that can undergo charge-transfer(CT) transitions determined by the degree of electron delocalization betweenthe phenolate oxygen (donor group) and nitro group (acceptor). Herewe have studied four different NPs: 4’-nitro-[1,1’-biphenyl]-4-olate (1),7-nitro-9H -carbazol-2-olate (NH linker, 2), 7-nitrodibenzo[b,d]furan-3-olate (oxygen 3), 7-nitrodibenzo[b...
In the title compound, C14H12ClN3O3S, the fused five- and six-membered rings are folded slightly along the common edge, forming a dihedral angle of 3.2 (1)°. The mean plane through the indazole system makes a dihedral angle of 30.75 (7)° with the distant benzene ring. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules, forming a two-dimensional network parallel to (001).
