Bakuchiol derivatives as novel and potent cytotoxic agents: A report
摘要:
A library of 28 compounds comprising of acyl, amino, halo, nitro, styryl and cyclized derivatives of bakuchiol have been evaluated against a panel of eight human cancer cell lines. Bioevaluation studies have resulted in the identification of potent cytotoxic molecules exhibiting concentration dependent growth inhibition against leukemia cancer cells with best results observed for compounds 17 and 22 exhibiting IC50 1.8 and 2.0 mu M respectively. As evident from various biological end-points, inhibition of cell proliferation by inducing G2/M cell cycle arrest, mitochondrial membrane disruption followed by DNA fragmentation and apoptosis is demonstrated.

Several derivatives of bakuchiol, a meroterpenoid from Psoralea corylifolia Linn., have been prepared and evaluated for insect juvenile hormone activity against Dysdercus koenigii nymphs. Almost all of these were found to be more active than the standard farnesyl methyl ether, while some of these proved to be many times more potent.

Novel bisstyryl derivatives of bakuchiol using Heck coupling reaction as the key step were synthesized and screened against a panel of six oral cavity pathogens for their antimicrobial activity. Four compounds (9-12) showed two to fourfold and four to eightfold better activity (MIC 0.25-16 mu g/ml) than bakuchiol and triclosan respectively. These compounds effectively inhibit the biofilm formation of single and multiple species at 2 - 8 x MICs. 4- and 4'-Hydroxy/methoxy styryl moieties of the bakuchiol derivatives play a pivotal role towards the activity as established in the SAR studies. Mechanism of action studies revealed microbial membrane structure disruption as the probable mode of action of these compounds. (C) 2010 Elsevier Masson SAS. All rights reserved.
Anti-proliferative evaluation of monoterpene derivatives against leukemia
The cure rate of pediatric acute lymphoblastic leukemia (ALL) has significantly improved in the past thirty years, however not all patient cohorts respond well to current chemotherapy regimens. Among the high risk patient cohort is infants with MLL-rearranged (MLL-r) B-ALL, which remains dismal with an overall survival rate <35%. Our program is interested in identifying new molecular scaffolds to better understand the underlying mechanisms and ultimately provide new targeted treatments. Based on a phenotypic screen, phenolic natural products were identified as promising scaffolds for further chemical evaluation. Herein we disclose the effects of a potent anti-proliferative compound 31 against human ALL leukemia cellular models. (C) 2016 Elsevier Masson SAS. All rights reserved.
