    COMPUTATIONAL ANALYSIS OF PHYTOCOMPOUNDS WITH 1, 3 - Β-D-GLUCAN SYNTHASE FOR ANTIDERMATOPHYTIC ACTIVITY
    (2014-02-27) M, Jeyam; M, Arangaraj; P, Ravikumar; G, Shalini
    Skin diseases are the most common infection in humans as well as in animals caused by fungi like yeast, mould and dermatophytes. In this study, in silico analysis of 20 phytocompounds was carried out for their efficacy as antidermatophytic agents using the receptor 1, 3 - β -D-Glucan synthase. The 3D structure of the receptor obtained using Modeller9V8 was validated with Procheck, where Ramachandran plot showed 80.3% of residues in the most favoured region. The phytocompounds and the drugs Echinocandin B and Caspofungin were docked with 1, 3 - β -D-Glucan synthase using Glide. Though all the 20 compounds exhibited lesser energy than both Echinocandin B (-3.3Kcal/mol) and Caspofungin (-1.68 Kcal/mol), Quercetin-3-O-rutinoside exhibited very less energy (-11.56 Kcal/mol). Further, comparing to synthetic drugs, the entire compounds selected for this study showed high interaction with the modeled protein. Hence, the present study concludes that the efficacy of all phytocompounds used in this study act against dermatophyes and which will be very helpful to the researchers working in the area of dermatophye drug developments

    WHEAT SEEDLINGS AS FOOD SUPPLEMENT TO COMBAT FREE RADICALS: AN IN VITRO APPROACH
    (2015-10) P, Ravikumar; G, Shalini; M, Jeyam
    The present study was designed to evaluate the antioxidant activity of 5 organic solvent extracts (petroleum ether, n-hexane, chloroform, ethyl acetate and methanol) of wheat grains, 3, 5 and 7 days old wheat seedlings. To determine the antioxidant activity of five extracts of four different samples, 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, total phenolic content and ferrous reducing power ability were carried out. 1,1-Diphenyl-2-picrylhydrazyl radical scavenging effect of chloroform and ethyl acetate extracts of 3 days old wheat seedlings was higher than wheat grains. Chloroform, ethyl acetate and methanol extracts of 3 days old wheat seedlings exhibited higher 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging effcet than extracts of other samples. The phenolic content was high in chloroform, ethyl acetate and methanol extract of 5 days old wheat seedlings. When compared with wheat grain, reducing power ability was high in chloroform, ethyl acetate and methanol extract of wheat seedlings, especially in 3 and 5 days old wheat seedlings. From the above results, it was concluded that chloroform, ethyl acetate and methanol extract of 3, 5 and 7 days old wheat seedlings showed better antioxidant activity than the wheat grain extracts. Hence, the results of the present study suggest the intake of wheat seedlings as a food supplement to combat the diseases caused by free radicals.
