Abstract
A cascade hexadehydro-Diels-Alder (HDDA)/[3 + 2] cycloaddition reaction between tetrayne and N,N'-cyclic acylhydrazone is described. This strategy allows the efficient construction of fully substituted 2,3-dihydro-1H-indazole scaffolds which have insecticidal activity against the third instar larvae of Mythimna separata.

Abstract
A simple and tuned synthesis of a 2H-indazole skeleton under metal-free conditions was developed. Under visible-light irradiation at room temperature, 2-((aryl/alkyl/H)ethynyl))aryltriazenes reacted with arylsulfinic acids to afford 3-functionalized 2H-indazoles without extra photocatalyst via an electron donor-acceptor complex. In the presence of arylsulfinic acid, 2-(ethynyl)aryltriazenes underwent an intramolecular oxidation/cyclization to provide 2H-indazole-3-carbaldehydes at 50 °C in air.

Abstract
A copper-catalyzed C3 amination of 2H-indazoles with 2H-indazoles and indazol-3(2H)-ones under mild conditions was developed. A series of indazole-containing indazol-3(2H)-one derivatives were produced in moderate to excellent yields. The mechanistic studies suggest that the reactions probably proceed through a radical pathway.

Abstract
Fischer indole synthesis of indole by using phenyl-hydrazine and acetaldehyde resulted 1H-Indole while phenyl-hydrazine reacted with malonaldehyde gives 1H-Indole-3-carbaldehyde. Also Vilsmeier-Haack formylation of 1H-Indole gives 1H-Indole-3-carbaldehyde. 1H-Indole-3-carbaldehyde were oxidized to form 1H-Indole-3-carboxylic acid. 1H-Indole reacted with excess of BuLi at -78 °C using dry ice also gives 1H-Indole-3-carboxylic acid. Obtained 1H-Indole-3-carboxylic acid was converted to ester and ester in to acid hydrazide. Finally 1H-Indole-3-carboxylic acid hydrazide reacted with substituted carboxylic acid gives microbial active indole substituted oxadiazoles. Synthesized compounds 9a-j showing promising in vitro anti microbial activities against S. aureus bacteria compared with Streptomycin. Compound 9a, 9f and 9g showing activities against E. coli compared with standards. Compound 9a and 9f are found potent active against B. subtilis compared with reference standard while compound 9a, 9c and 9j active against S. typhi.

Antiproliferative and apoptotic activity of new indazole derivatives as potential anticancer agents. Arch Pharm (Weinheim) 2020; 353:e2000173.

Abstract
To develop potent and selective anticancer agents, a series of novel polysubstituted indazoles was synthesized and evaluated for their in vitro antiproliferative and apoptotic activities against two selected human cancer cell lines (A2780 and A549). Several compounds showed an interesting antiproliferative activity, with IC50 values ranging from 0.64 to 17 µM against both cell lines. The most active indazoles were then tested in different pharmacological dilution conditions, adding five new cell lines (A2780, A549, IMR32, MDA-MB-231, and T47D) as targets, confirming their antiproliferative activity. Furthermore, selected compounds were able to trigger apoptosis to a significant extent and to cause, in part, a block of cells in the S phase of the cell cycle, with a concomitant decrease of cells in the G2/M and/or G0/G1 phases and the generation of hypodiploid peaks. However, molecule 7d caused a great increase of cells in G2/M and the appearance of polyploid cells. Altogether, our results suggest a good pharmacological activity for our selected polysubstituted indazoles, which are suggestive of a preferential mechanism of action as cell cycle-specific antimetabolites or as an inhibitor of enzyme activities involved in DNA synthesis, except for 7d, which, on the contrary, seems to have a mechanism involving the microtubule system.
