The molecular spectroscopic investigations have been carried out to study the antibiotic activity of the Isonicotino hydrazide. The activity of the compositional parts was tested by fundamental modes of vibrations of various bonds of the molecule. The chromophores action for the inducement of the antibiotic activity of the compound was analyzed from the electronic excitation absorption peaks. The s-bond, p-bond and d-bond interaction lobes were identified and the energy exchange between the orbitals was investigated from frontier molecular orbital profile. The asymmetrical charge distribution among different entities of the molecule for the perseverance of anti tuberculosis mechanism was recognized. The NMBO interaction energy transition outline was organized by the NBO calculation adapted with Gaussian calculations and the exchange of maximum energy transaction among various functional groups for the incentive of antibiotic were determined. The second order Polarizability of the compound emphasized the consistency of the antibiotic activity of the molecule. Thermodynamic activity of the molecule with respect to the temperature was stressed the decomposition rate and Gibbs free energy helped to determine the steadiness of the compound. The inhibition catalytic efficiency of the title molecule was fully tested by molecular docking study.

The purpose of the present study was to assess the effect of resveratrol (RSV) on the pharmacokinetics of naproxen (NAP) in rats. A single dose of RSV 30mg/kg was administered once during treatment phase. A single dose of NAP 25mg/kg was administered after RSV treatment. The blood samples were collected after NAP dosing at predetermined time intervals and analyzed by HPLC. In comparison with the control, RSV pretreatment significantly enhanced maximum plasma concentration (Cmax), area under the curve (AUC), and half life (t1/2) and significantly decreased apparent oral clearance (CL/F) and apparent volume of distribution (Vd/F), while there was no significant change observed in time to reach maximum concentration (tmax) of NAP. The results suggest that the altered pharmacokinetics of NAP might be attributed to RSV-mediated inhibition of CYP1A2 enzyme. Therefore, combination therapy of NAP along with RSV may represent a novel approach to reduce dosage and results in reduced gastrointestinal side effects of NAP.

Oral drug delivery is the most widely utilized route of administration, among all the routes of administration. That has been explored for the systemic delivery drug through different pharmaceutical dosage forms. It can be said that at least 90%of all drugs used to produce systemic effect is by oral route. Conventional oral drug delivery systems are known to provide an immediate release of drug, in which one cannot control the release of the drug and effective concentration at the target site.
