Phytochemicals from several herbaceous and spice plants have been reported to have defense properties against various diseases. Potential of some of such plants like Allium sativum, Curcuma longa, Boerhaavia diffusa, Pterocarpus marsupium and Zingiber officinale in cancer therapy has already been proved. The state of Kerala in southern India hosts large number of medicinal herbs and is also referred as a hotspot of biodiversity. The current study aimed at computational screening of potent lead molecules from ten selected medicinal plants and five spices widely used in Kerala, which are rich in biological diversity and its traditional values. Even though, the anticancer properties of all these plants and spices were reported, their mode of action and target molecules is not well explained. Hence, the interaction of these compounds with anti-apoptotic proteins Bcl-2 and Bcl-XL are studied and discussed in this paper. The -CDOCKER energy, -CDOCKER interaction energy, Hydrogen bonds, binding energy, and complex energy were predicted through molecular docking studies. Based on binding energy and CDOCKER scores, the active components...

Larrea divaricata Cav. (Zygophyllaceae) is an autochthonous plant of South America, widely distributed in Argentina. It is used in folk medicine as an anti-inflammatory drug. By other way, presents well documented antitumoral and immunomodulatory effects. Nordihydroguaiaretic acid (NDGA), an antioxidant compound, had been previously described in this plant. Nowadays a formulation for hair growth based on an extract of L divaricata is commercialized in Argentina. Taken these into account, the objective of this work was to determine the systemic and local toxicities of the aqueous extract of L divaricata, by giving it under oral and topical administration. Also, it was proposed to analyze the participation of NDGA in the systemic toxicity of the plant extract. The extract presented low acute toxicity, and the histopathological examination of the tissues did not show any signal of toxicity at the same time that did not affect biochemical parameters except eosinophils which were decreased by the treatment. Which is more; the extract did not exert dermatological or ocular irritation. It is important to...

The present study is about the pharmacognostic and phytochemistry study on Dillenia indica Linn. Dillenia indica is commonly known as chalta or chilta in Hindi. It is a medium sized tree, a native of South eastern Asia, India, Bangladesh, East Srilanka, South western China and Vietnam. The plant is evaluated for understanding the pharmacognostic and Phytochemical characteristics of the leaf. The physicochemical parameters were evaluated which revealed the moisture content as 10.71%. Water soluble and alcohol soluble extractives was found to be 11.97% and 42.32% respectively. Total ash content, water soluble ash content and acid insoluble ash content was found to be 17.48%, 14.03% and 10.56% respectively. Phytochemical analysis revealed the presence of Alkaloids, Glycosides, Steroids, Flavonoids, Tannins, Saponins and Phenolic compounds. TLC and HPTLC analysis revealed the presence of various phyto-constituents along with Flavonoids, Steroids and Amino acids. HPTLC analysis revealed the presence of Quercetine, Kaempferol, Cholesterol and Glutamic acid. Detection was done under 254 and...

Vinca alkaloids are a subset of drugs obtained from the Madagascar periwinkle plant, Catharanthus roseus and have hypoglycemic as well as cytotoxic effects. They are used for treating diabetes, high blood pressure and have been used as disinfectants. The vinca alkaloids are important for being cancer fighters, as they work by inhibiting the ability of cancer cells to divide. Upon acting on tubulin, they prevent the formation of microtubules, an essential component for cellular division. . There are four major vinca alkaloids in clinical use: Vinblastine (VBL), vinorelbine (VRL), vincristine (VCR) and vindesine (VDS). Vinblastine is most often used to treat breast cancer and germ cell tumors. Vinorelbine has exhibited significant antitumor activity in patients with breast cancer and anti proliferation effects on osteosarcoma (bone tumor cells). Vincristine is FDA approved to treat Wilm’s tumor, acute leukaemia and other lymphomas. Vindesine is used in the treatment of melanoma, lung cancers and uterine cancers. Vinflunine is used for the treatment of second-line transitional cell carcinoma of the urothelium. In the...

Herein method for the synthesis of substituted 1,2-benzoxazolone (8a-f) and 3-chloro-1,2-benzoxazole (9a-f) derivatives has been described. A new scheme has been adapted for the construction of 1,2-benzoxazole ring from salicylic acid and its derivatives which leads to the formation of series of 5,6 and 7 substituted title compounds. Synthesized compounds were characterized by IR, 1H-NMR and Mass spectral analysis. Spectral data confirmed the compounds formation. Final compounds (8a-f) and (9a-f) were screened for their in-vivo analgesic activity by acetic acid induced writhing method in rats and anti-inflammatory activity by carrageenan-induced paw edema model. Among the compounds screened compound 8a and compound 9c showed good analgesic activity of about 45% (writhing mean 8.9) and 54% (writhing mean 7.5) inhibition respectively at 5 mg/Kg po dosage. Compounds 8b and 9b (both having inhibition edema of 66.1%) showed significant anti-inflammatory activity. Other derivatives exhibit moderate to good analgesic and anti-inflammatory...
