An increasing incidence of deaths due to tuberculosis and the known drawbacks of the current existing drugs including the emergence of multi drug-resistant strains have led to a renewed interest in the discovery of new anti-tubercular agents with novel modes of actions. The recent researches focused on natural products have shown a useful way to obtain a potentially rich source of drug candidat...

Recent studies have indicated that 1, 4-dihydropyridine-3, 5-dicarboxamidederivativesshow significant anti-tubercular activity. In this research, new derivatives of 1, 4-dihydropyridine were designed and synthesized using Hantzsch condensation in which dicyclohexyl and different dicyclohexylcarbamoylwere substituted at C-3 and C-5 positions of the DHP ring.In addition, 4 (5)-chloro-2-methyl-5 (...

The bibliography includes 97 references which have been published during the period from 1980 to 2013. The covered biological activities of the title compounds include antioxidant, anticonvulsant, therapeutic, anthelmintic, anti-tubercular, antiviral, anti-inflammatory, anticancer, anti-HIV,...

Joining the global fight against Tuberculosis, world's most deadly infectious disease, herein we present design and synthesis of novel isatin-nicotinohydrazide hybrids (5a–m 9a–c) as promising anti-tubercular antibacterial agents. The activity target was evaluated drug-susceptible M. tuberculosis strain (ATCC 27294) where 5d, 5g 5h were found to be potent INH with MIC = 0.24 µg/mL, also Isoniaz...

Background: Aim of current study was to determine the clinical characteristics, radiological, laboratory features and anti-tubercular drug sensitivity in new smear positive (category I) pulmonary tuberculosis cases in a tertiary care dedicated TB OPD, Delhi. Methods: The study was a cross-sectional observational study and consists of 100 cases of new smear positive pulmonary tuberculosis cases ...

The vertebrate diencephalic A11 system provides the sole dopaminergic innervation of hindbrain and spinal cord and has been implicated in modulation of locomotion and sensory processes. However, the exact contributions of sensory stimuli and motor behavior to A11 dopaminergic activity remain unclear. We recorded cellular calcium activity in four anatomically distinct posterior tubercular A11-ty...

A series of 1,2,3-trisubstituted indolizines (2a–2f, 3a–3d, and 4a–4c) were screened for in vitro whole-cell anti-tubercular activity against the susceptible H37Rv multidrug-resistant (MDR) Mycobacterium tuberculosis (MTB) strains. Compounds 2b–2d, 4a–4c active H37Rv-MTB strain with minimum inhibitory concentration (MIC) ranging from 4 to 32 µg/mL, whereas 4a–4c, ethyl ester group at 4-position...

OBJECTIVE This study aims to evaluate the diagnostic efficacy of adenosine deaminase in tubercular effusions. METHODS This study was conducted at the Department of General Medicine and Cardiovascular and Thoracic Surgery, SKIMS, for a period of two years between November 2008 and November 2010. A total of 57 patients presenting with pleural effusions during the two-year study period, who pres...

a new series of transition metal complexes of co(ii), ni(ii), cu(ii) and zn(ii), has beensynthesized from the knoevenagel condensate schiff base ligand(l) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. structural features were determinedby spectral and analytical techniques. square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

Abstract Despite the remarkable progress in diagnostic and antifungal drugs research in past 10 years ,still complexity of the characteristics of patients continue to make the management of fungal infection is a great challenge .1,2,4-triazole compounds not only offer an interesting chemistry but also their various derivatives possesses diverse chemotherapeutic activity. The recent literatures ...
