GC- MS SCREENING AND IN-SILICO PREDICTION OF PILA GLOBOSA EXTRACT AGAINST THE BONE DISEASES IN CALCITONIN RECEPTOR

Abstract

India’s flora and fauna has diverse medicinal properties and constitutes the major portion of our traditional medicine system. One among them is snails. Snails have a long history of being used for treating diseases in traditional medicinal systems around the world including India and China. Pila globosa is one of the largest land snails, mainly used as food. Here in this study, the gas chromatography and mass spectrometry discovered the presence of thirteen bio active constituents with various medicinal applications. The constituent Stigmasta-4, 22-dien-3-beta-ol had the highest retention time and exhibited a efficient binding with the human protein calcitonin receptor ectodomain. The calcitonin receptor types is expressed widely in various tissues and cells but most importantly in the osteoclates and hence a very important receptor in the treatment for bone disorders. The binding of the Pila globosa snail constituent with the human calcitonin receptor proved that a novel drug can be developed from the snail for the treatment of bone disorders such as osteoporosis, hypercalcemia of malignancy and paget’s disease. In addition to that, the snail extract exhibited no cytotoxicity and an efficient antioxidant property against DPPH and H2O2 free radicals. The FTIR analysis revealed the snail contained biologically significant functional groups with properties suitable for a drug and prevalent in most of the pharmaceutical drugs. Thus, these results imply the safety and efficacy of the snail Pila globosa for a novel drug development.
