Structural, spectral and bioactivity scores of 5,6 Dimethyl 1-H benzotriazole monohydrate: experimental and DFT study
Abstract
Bioactive molecules are chemical molecules which produced by living organism that exert a biological effect on other organisms. Benzotriazole derivatives are nitrogen containing bicyclic ring structure and have been confirmed for many biological activities, such as antibacterial, antifungal, anticancer, anti-inflammatory, analgesic, antimalarial and antitubercular activity. In the present work throws different derivatives of benzotriazole and their related to biological activity. Benztriazole derivatives have effectively confirmed as antimicrobial activity. Bioactive molecule 5,6 Dimethyl 1-H Benzotriazole Monohydrate (DMBM) has been performed by the basis set of B3LYP/6-31(d,p) using DFT. Global minimum energy of 5,6 Dimethyl 1-H Benzotriazole Monohydrate is -551.095102444 a.u. Inter and intra-molecular hydrogen bonding are discussed by using Natural Bond Orbital (NBO) analysis. This result has the existence of strong N3….H15-O13 whose energy is about 0.11 kJ/mol which supports the inter-molecular hydrogen bonding. Energy gap between the HOMO and the LUMO is 0.19891 eV. Natural Coordinate Analysis (NCA) has been used as the tool for Spectral interpretations. Red shifting by ~54 cm-1 ascribed the level of inter-molecular N-H…O hydrogen bonding. Highly effective inhibition against Salmonella paratyphi with a zone diameter of 20mm. Optical transmittance has been performed using UV-visible absorption spectra. The maximum absorption and transmittance peak in the UV–vis spectrum predicts electronic transitions at 199 nm and 243 nm.
