Thin Layer Densitometric Determination of Rotenone and Deguelin

Journal of AOAC INTERNATIONAL, 1969
Abstract Rutenone and deguelin are separated by chromatography on silver nitrate-impregnated silica gel G with chloroform acetone: acetic acid (196:3:1) solvent system. Glass plates, 20 × 20 cm, are coated with a special spreader producing a 0.25 mm layer and a 1.00 mm band at the upper end.

Heat shock protein 90: biological functions, diseases, and therapeutic targets

MedComm, Volume 5, Issue 2, February 2024.
Targeting the dynamic cycling of HSP90 and its interaction with co‐chaperones can promote protein maturation and client protein degradation, potentially offering effective antineoplastic strategies. Abstract Heat shock protein 90 (Hsp90) is a predominant member among Heat shock proteins (HSPs), playing a central role in cellular protection and ...

Antiproliferative Activities and SwissADME Predictions of Physicochemical Properties of Carbonyl Group‐Modified Rotenone Analogues

ChemistryOpen, Volume 13, Issue 1, January 2024.
Rotenone derivatives were synthesized through modifications of the carbonyl group and their antiproliferative activities were evaluated against various cancer cell lines (MCF‐7, A549, and HCT116). The physicochemical properties and drug‐likeness of the derivatives were evaluated using the SwissADME webtool.
