Abstract :

Recently Betulinic acid, a naturally occurring plant secondary metabolite, has gained significant attention due to its antiproliferative activity over a range of cancer cells. In our previous study, we have reported a promising betulinic acid analogue (2c) with better therapeutic efficacy than the parent molecule to colon carcinoma cells. Despite its impressive biological activity, poor water solubility and low bioavailability creates difficulties in its pharmacological activity. To overcome these lacunas and making it a promising drug candidate we have formulated PLGA encapsulated 2c in the present study followed by evaluated its in vitro and in vivo therapeutic efficacy in both mice and rat colon carcinoma model. Nanoformulated drug delivery provides several advantages over free drug such as large loading capacity, minimum drug loss, sustained drug release and long-term in vivo stability. Additionally, due to enhanced permeability and retention effect in the tumor microenvironment, nano sized drug molecules preferentially penetrate the tumor vessel and retain at that site which ensures minimum cytotoxicity to normal cells. Herein we observed that nanoformulation of 2c developed a perfect nano size sphere with smooth surface area, effective cellular uptake, 8% drug loading and in vitro sustained drug release profile. In vitro antiproliferative activity significantly enhanced over free drug, which is measured by MTT assay, Annexin V positivity, JC1 analysis, DNA degradation and cell cycle study. In vivo therapeutic potential measured in mice and rat model also reflects its ability as a promising drug candidate for treatment of colon carcinoma and future potential clinical aspect.
