MOLECULAR DOCKING, PHARMACOPHORE MODELLING AND 3D QSAR ANALYSIS OF NOVEL CHALCONE DERIVATIVES
Chalcone based structures have many interesting biological properties like anti-malarial, anticancer, antiviral, antibacterial, antifungal, anti-hyperglycaemic and photo-cytotoxicity activities. In this study, the novel chalcone derivatives (1a-1l) have been synthesized and investigated for antimicrobial activities. The MIC results of antimicrobial activities reveal that one of the chalcone deriva...

TRITERPENE ACIDS FROM n-HEHANE EXTRACT 0F ALBIZZIA LEBBECK BENTH.
Two triterpine acids like 2α, 19α- dihydroxy – 3-oxo-12- ursen- 28-oic acid (1), 2α, 16α, 19α- trihydroxy – 3-oxo-12- ursen- 28-oic acid (2) were isolated from the n-hexane soluble fractions of a methanol extract of the root of Albizzia lebbeck Benth. The structures of the isolated compounds were elucidated as by extensive spectroscopic studies, including high field NMR analyses. This i...

SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL EVALUATION OF NOVEL IMIDAZO THIAZOLE CHALCONES AS ANTIOXIDANT AGENT
A series of condensed Imidazo [2, 1-b] [1,3] thiazole Chalcones have been synthesized by Claisen–Schmidt condensation reaction. Imidazo thiazole Chalcones are associated with immense biological activities. Novel Imidazo thiazole-based chalcones were synthesized using Imidazo thiazole-3-carboxaldehydes and various acetyl ketones in PEG-400. The structures of the compounds were characterized by I...

THERAPEUTIC POTENTIAL OF CUCURBITS AGAINST RADIATION INDUCED INFLAMMATION AND DAMAGE IN MICE GUT
Whole body or local irradiation to gut is known to induce significant damage to gut epithelium and crypt stem cells. A large population of microbes in the gut remains unaffected. We hypothesize that the modifications in diet and enteric microbial population may provide a non-toxic mechanism to counter radiation induced health deficit, especially in the gut and therefore investigated the effect of ...

IN-SILICO MOLECULAR SCREENING OF NATURAL PLANT PRODUCTS FOR THE IDENTIFICATION OF NOVEL POTENTIAL CHEMOTHERAPEUTIC AGENTS AGAINST BREAST CANCER
In-silico computational approaches help in ascertaining drug targets via bioinformatics tools. HER2 is the most valuable therapeutic target for breast cancer therapy. The overexpression of HER2 protein plays a very critical role in the progression of breast cancer. Plant-derived natural products have received increasing attention over the past 20-30 years for their potential as novel therapeutic a...

CHARACTERIZATION AND STABILITY OF EXTRACELLULAR ALKALINE PROTEASES FROM HALOPHILIC AND ALKALIPHILIC BACTERIA ISOLATED FROM SALINE HABITAT OF LONAR SODA LAKE, INDIA
Culture dependent phenotypic characterization analyses were applied to study the protease producing bacteria from Indian Soda (Lonar crater). The uniqueness of the Lonar lake water is its salinity and alkalinity. A total of one hundred and fourteen bacterial cultures were isolated from the water and sediment samples collected from the hyper alkaline saline environment of Lonar lake. The thirty two...

INCREASED PROPERTIES AND CITOCOMPATIBILITY OF ZINC OXIDE-MAGNESIUM CEMENT
Zinc oxide-magnesium has been used in dentistry with limitations especially related to its high acidity and low biocompatibility. The objective of this study was to develop cement based on nano-hydroxyapatite (nHA), chitosan as more biocompatibility agents to increase zinc oxide-magnesium cito-compatibility. The formulations prepared were: 1. Complete cement (HCP) with nHA, zinc oxide-magnesium, a...
