Background: Fungi performing a wide range of function in soil by secreting low molecular
weight compound known as secondary metabolites. S. rolfsii is a soil borne phytopathogenic
fungi was used for the production of bioactive compounds.
Objective: The present study belongs to evaluate the anticancer potentials of a secondary metabolites
isolated from S. rolfsii, their multidrug resistance (MDR), and molecular docking study.
Method: (1S,3R,4R,5R,E)-3-(3-(3,4-Dihydroxyphenyl)acryloyloxy)-1,4,5 trihydroxycyclohexanecarboxylic
acid (1), or best known as chlorogenic acid, was isolated from the ethyl acetate fraction
of crude secondary metabolites produced by the soil borne Fungus Screlotium rolfsii. Structure of
chlorogenic acid (1) was confirmed by means of FT-IR, 1H NMR, 13C NMR, and mass spectrometry
as well as by melting point.
Results: Effect of compound 1 on the reversion of multidrug resistant (MDR) mediated by Pglycoprotein
(P-gp) against cancer cells was evaluated with a rhodamine-123 exclusion screening
test on human mdr1 gene transfected mouse gene transfected L5178 and L5178Y mouse T-cell
lymphoma. Compound 1 was also evaluated for Anti-proliferative effect on the L5178 mouse Tcell
lymphoma cell line.
Conclusion: Results from the present investigation revealed that compound 1 exhibits excellent
MDR reversing effect in a dose-dependent manner against mouse T-lymphoma cell line. Compound
1 also showed anti-proliferative effect on L5178Y mouse T-lymphoma cell line.
