Ashmawy NS, El-labbad EM, Hamoda AM, El-Keblawy AA, El-Shorbagi ANA, Mosa KA, Soliman SSM. The Anti-Candida Activity of Tephrosia apollinea Is More Superiorly Attributed to a Novel Steroidal Compound with Selective Targeting. PLANTS 2022; 11:plants11162120. [PMID: 36015423 PMCID: PMC9415581 DOI: 10.3390/plants11162120] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 08/02/2022] [Accepted: 08/08/2022] [Indexed: 11/16/2022]
Abstract
Tephrosia is widely distributed throughout tropical, subtropical, and arid regions. This genus is known for several biological activities, including its anti-Candida activity, which is mainly attributed to prenylated flavonoids. The biological activities of most Tephrosia species have been studied, except T. apollinea. This study was conducted to investigate the underlying anti-Candida activity of T. apollinea, wildly grown in the United Arab Emirates (UAE). The T. apollinea plant was collected, dried, and the leaves were separated. The leaves were ground and extracted. The dried extract was subjected to successive chromatography to identify unique phytochemicals with a special pharmacological activity. The activity of the compound was validated by homology modeling and molecular docking studies. A novel steroidal compound (ergosta-6, 8(14), 22, 24(28)-tetraen-3-one) was isolated and named TNS. In silico target identification of TNS revealed a high structural similarity with the Candida 14-α-demethylase enzyme substrate. The compound exhibited a significant anti-Candida activity, specifically against the multi-drug-resistant Candida auris at MIC50, 16 times less than the previously reported prenylated flavonoids and 5 times less than the methanol extract of the plant. These findings were supported by homology modeling and molecular docking studies. TNS may represent a new class of Candida 14-α-demethylase inhibitors.

Saudi J Biol Sci 2015; 22:164-7. [PMID: 25737647 PMCID: PMC4336440 DOI: 10.1016/j.sjbs.2014.12.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2014] [Revised: 12/14/2014] [Accepted: 12/15/2014] [Indexed: 11/05/2022] Open
Abstract
Tephrosia calophylla Bedd. (Fabaceae) is an endangered tropical plant endemic to southwestern Ghats, India. The objective of this study was to contribute to the characterisation of the diversity of this rare species, which is necessary for its future conservation. Accordingly, microsatellite markers were designed, and their ability to detect polymorphisms was determined. Nine microsatellite markers were developed using genomic libraries, and all of the markers were successfully amplified in 42 individuals. Three to nine alleles per locus were observed, and the heterozygosity of the loci ranged from 0.381 to 0.905. The nine newly developed polymorphic markers recognise a sufficient number of varying loci to perform further studies on the conservation and breeding of this medicinal cultivar.
