Abstract
Multidrug resistance mechanism of microorganisms towards conventional antimicrobials nowadays faces a common health problem. So, searching and development of new antibacterials are in the frontier areas of biochemistry. Functionalizations of various natural products or synthesis of compounds through molecular modeling followed by virtual screening are the ways to obtain potential leads. Chrysin is one of the plant secondary metabolites and is ubiquitously present in majority of plants. It has multi-dimensional potentiality however, with a very low bioavailability causing a very low efficacy. Very few chrysin derivatives possessing antimicrobial activity with a low anti-biofilm efficacy have been found in the literature. Thus, it has been attempted to synthesize a series of new chrysin derivatives (CDs). In this study, twenty-two new derivatives have been synthesized via its 7-OH modulation and antibiofilm activity was evaluated against a model bacterium viz. Escherichia coli MTCC 40 (Gram negative). Eleven CDs coded as 2a, 2b, 2c, 2e, 2f, 2g, 2h, 2i, 3j, 3k and 3l have been found more potent compared to chrysin (precursor of CDs) against planktonic form of E. coli. Biofilm inhibition studies indicated a noteworthy results for 2a (93.57%), 2b (92.14%), 2f (92.14%) and 3l (93.57%) compared to chrysin (33.57%). E. coli motility was also highly restricted by 2a, 2b, 2f and 3l than chrysin at their sub-inhibitory concentrations. Solubility studies indicated an extended-release of 2a, 2b, 2f and 3l in physiological systems. Relatively higher bioavailability of 2a, 2b, 2f and 3l than chrysin was revealed from the dissolution experiments and was further validated through in silico ADME-based SAR analysis. Hence, this study is more interesting in regard to antibacterial potentiality of chrysin derivatives against Escherichia coli MTCC 40 (Gram negative). Thus, this article might be useful for further design and development of new leads in the context of biofilm-associated bacterial infections.
