Journal ArticleDOI
Design, synthesis, and evaluation of novel 6-chloro-/fluorochromone derivatives as potential topoisomerase inhibitor anticancer agents.
TL;DR: The compounds displayed promising anticancer activity under these test systems and shall serve as useful 'leads' for further design.
Journal ArticleDOI
Evaluation of intrabony defects treated with platelet-rich fibrin or autogenous bone graft: A comparative analysis.
TL;DR: The bivariate correlation results revealed that any of the two radiographic techniques (IOPA and OPG) can be used for analysis of the regenerative therapy in IBDs.
Journal ArticleDOI
Unusual conversion of substituted-3-formylchromones to 3-(5-phenyl-3H-[1,2,4]dithiazol-3-yl)chromen-4-ones: a facile and efficient route to novel 1,2,4-dithiazoles
Tilak Raj,Mohan Paul S. Ishar,Vivek K. Gupta,Ajay Pal Singh Pannu,Priyanka Kanwal,Gurpinder Singh +5 more
TL;DR: Substituted 3-formylchromones react with 2-phenyl-4-dimethylamino-1-thia-3-azabuta-1,3-diene ( 4 ) or thio-benzamide ( 7 ) by heating their toluene solution in a sealed tube to give novel substituted 3-(5phenyl)-3 H -[1,2,4]dithiazol-3yl)chromen-4ones ( 6a − e ) in high yields as discussed by the authors.
Journal ArticleDOI
Intramolecular low-temperature 1,3-dipolar cycloadditions of nitrones: synthesis of chromano-heterocycles
Gurpinder Singh,Mohan Paul S. Ishar,Vivek K. Gupta,Gurmit Singh,Mohit Kalyan,Surinderjit Singh Bhella +5 more
TL;DR: In contrast to the reported facile intramolecular 1,3-dipolar cycloadditions of in-situ generated nitrone on heterocyclic systems, reactions of 2-(N-allyl/crotyl/cinnamyl-anilino)-3-formylchromones with N-phenyl-/methylhydroxylamine under comparable conditions, afford fused isoxazolidines only in low to moderate yields; the corresponding amides derived from rearrangement of in situ generated nitrones are formed as major products RE
Journal ArticleDOI

TL;DR: In this article, a stereoselective 1,3-dipolar cycloadditions of C -(3-indolyl)- N -phenylnitrone (10) with different mono-substituted, disubstitized and cyclic dipolarophiles under mono-mode microwave irradiation were carried out to obtain substituted 3-(indol-3′-3-yl)- N-phenyl-isoxazolidines (16−22).
