A number of linezolid-like oxazolidino-sulfonamides (7a-y and 8a-b) were designed and synthesized with a view to develop antimicrobial agents with improved properties. Most of the synthesized compounds showed good to moderate activity against a panel of standard Gram-positive and Gram-negative bacteria and fungal strains. The compounds 7i and 7v exhibited(More)
As a part of investigation of new anti-tubercular agents in this laboratory, herein we describe the synthesis of a new class of arylsulfonamido conjugated oxazolidinones. The in vitro activity of these conjugated (6a-f, 7a-d, 9a-c and 11a-c) molecules against Mycobacterium tuberculosis H(37)Rv by using rifampicin and linezolide as positive controls is(More)
In a one pot procedure, a series of novel hybrid heterocycles 6a-g and 7a-g were prepared by condensation of (3aS,4S,6S,6aS)-6-((1-(4-chlorophenyl)-1H-1,2,3-triazol-4-yl)methoxy)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole-4-carbaldehyde 5 with mercapto acids and primary amines in the presence of ZnCl2 under both microwave irradiation and conventional(More)
A series of β-carboline-benzimidazole conjugates bearing a substituted benzimidazole and an aryl ring at C3 and C1 respectively were designed and synthesized. The key step of their preparation was determined to involve condensation of substituted o-phenylenediamines with 1-(substituted phenyl)-9H-pyrido[3,4-b]indole-3-carbaldehyde using La(NO3)3·6H2O as a(More)
In an effort to discover new and effective chemotherapeutic agents from this laboratory for the treatment of tuberculosis, here in we describe the synthesis and biological evaluation of a series of novel benzothiadiazine 1,1-dioxide (BTD) based congeners by using rifampicin, streptomycin; ciprofloxacin and amphotericin as positive controls. Further, to(More)
In an effort to discover new anti-tubercular agents, a series of new diarylpyrrole-oxazolidinone conjugates have been designed and synthesized. The anti-tubercular activity of these new conjugates (4a-n and 5a-d) against Mycobacterium tuberculosis H37Rv and drug resistance strains such as M. tuberculosis Rif(R) and M. tuberculosis XDR are discussed, wherein(More)
The electrophoretic banding patternof esterases were examined in six different tissues of Pomacea paludosa and Pomacea canaliculata by using different inhibitors viz: pCMB, Paraoxon, Physostigmine, EDTA and AgNo3. Same esterolytic active zones were observed in Ctenidia and Mantle of both species, the maximum number of bands exhibiting in Ctenidia of(More)
Now day's computer vision techniques are used for analysis of traffic surveillance videos which is gaining more importance. This analysis of videos can be useful for public safety and for traffic management. In recent time, there has been an increased scope for analysis of traffic activity automatically. Computer based surveillance algorithms and systems(More)
A series of imidazo[2,1-b][1,3,4]thiadiazole-linked oxindoles composed of an A, B, C and D ring system were synthesized and investigated for anti-proliferative activity in various human cancer cell lines; test compounds were variously substituted at rings C and D. Among them, compounds 7(More)
Now a day's vehicle recognition has become a wide area of research. Vehicle recognition has several applications such as in automatic parking, toll gate management etc., Because of numerous applications, vehicle recognition in computer vision has become a research area in Intelligent Transport System (ITS). There are many different vehicles from different(More)
