Abstract
A major impediment for cancer chemotherapy is the development of multidrug-resistance (MDR). Continuous use of chemotherapeutic drugs during cancer therapy induces the expression of PGlycoprotein (P-gp, MDR1), an ATP dependant transporter, which in turn reduces the intracellular accumulation of chemotherapeutic drugs leading to MDR. Extensive research over the years has identified several potential P-gp inhibitors, both synthetic as well as natural origin, to overcome the MDR during cancer chemotherapy. In this review, we discuss the cellular pathways involved and transcription factors regulating the expression of P-gp. A number of phytochemicals are reported to inhibit P-gp activity and MDR1 expression; the structure-activity relationship (SAR) among the phytochemicals for P-gp inhibition and the effect of these phytochemicals on cellular signaling pathways regulating P-gp expression are discussed in detail. Moreover, structural biology and mutagenesis studies on P-gp along with docking studies throw light on the structural requirements for P-gp inhibition. Insight provided in the review about the phytochemicals molecular mechanism and SAR could catalyze the design of potent P-gp inhibitors in the future and could help to overcome MDR in cancer chemotherapy.
Keywords: Chemotherapy, Multidrug resistance (MDR), P-glycoprotein (P-gp), Phytochemicals, Structure Activity Relationship.

From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
