در این مطالعه بر هم کنش این چهار کمپلکس با dna تیموس گوساله توسط روش های اسپکتروفتومتری، فلوریمتری، دو رنگ نمائی دورانی، و ویسکوزیمتری بررسی شدند تا اثر استخلاف های متیل بر روی لیگاندهای فنانترولین بررسی گردد.
Aminothiazolylglycyl derivatives of carbacephems. I. Synthesis and antibacterial activity of novel carbacephems with substituted aminothiazolyl groups.
A series of new carbacephem compounds which have substituted aminothiazolylglycyl side chain have been prepared starting from corresponding carbacephems with aminothiazolylmethoxyimino group. Among them, the compound having 3,4-dihydroxybenzoyl group showed very sharp activity against Pseudomonas aeruginosa. Moreover, the optical resolution of alpha carbon of aminothiazolylglycyl moiety was car...
متن کاملSubstituted Septithiophenes with End Groups of Different Size: Packing and Frustration in Bulk and Thin Films.
We report on three different liquid crystalline compounds with a central septithiophene core and alkylated end groups of strongly increasing bulkiness. In principle, the thiophene cores prefer to pack parallel to optimize their π-π interactions, which becomes sterically impossible for the bulkier end groups. Using X-ray diffraction, we find that the way out of this packing dilemma is toward liq...
متن کاملSynthesis of Isocoumarins with Different Substituted Patterns via Passerini–Aldol Sequence
An efficient combination between the Passerini three-component reaction and aldol condensation has been developed for the synthesis of bicyclic isocoumarins with different substituted patterns via solvent-dependent domino pathways. These two operationally friendly methods simultaneously install C-O and C-C bonds in a one-pot manner, allowing the utilization of low-cost and readily accessible 2-...
