Abstract:
A new series of arylisoxazole-oxindole derivatives (6a-r) were synthesized and evaluated for their antiproliferative activity against human cancer cell lines including non-small cell lung (A549), cervical (HeLa), breast (MCF-7), and prostate (DU-145) cancer cell lines. The synthesized compounds (6a-r) demonstrated excellent to moderate cytotoxicity with IC50 values ranging from 0.82 to 3.69 μm. Some new compounds (6m-r) exhibited profound cytotoxicity better or similar to positive control. More particularly, the compound 6q possesses donating substituent like methoxy group presented at 5-position on D ring exhibited remarkable antiproliferative activity against A-549 (lung cancer) with an IC50 value 0.82 μm. Further studies to determine the mechanistic aspects of these conjugates are under progress.
Insights
Researchers developed novel arylisoxazole-oxindole derivatives with significant antiproliferative activity against various human cancer cell lines. Compound 6q showed potent lung cancer cell inhibition, indicating potential as a new cancer therapeutic agent.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
