Biologically active Pyrroles Год выпуска: 2014Автор: Meghasham NaruleИздательство: Scholars' PressСтраниц: 156ISBN: 9783639718430Описание Heterocyclic compounds have played an important role in the evolution of life, as dyes, drugs and are also used in many commercially important species. Pyrroles and their derivatives exhibit different important biological activities like antibacterial, antioxidant, cytotoxic, insecticidal, anti-inflammatory, anticoagulant, antiallergic, antiarhythmic, hypotensive and anticonvulsant etc. Benzylideneacetophenones play an ecological role in nature, in relation to plant colour. These brightly yellow coloured compounds are found in many plant organs, but most conspicuously in flowers. Benzylideneacetophenones contain reactive keto ethylenic (enone) group. The presence of enone fraction in the benzylideneacetophenones molecule confers antibiotic activity (bacteriostatics /bactericidal) upon it. This property is enhanced when substitution is made at the ?-(nitro and bromo) and ?-(bromo and hydroxylic) position. Some substituted benzylideneacetophenones and their derivatives, including some...

Юлия Добрый день, Юля! Я сегодня защитила диплом после вашего сопровождения на отлично :-) Хотела сказать Вам ОГРОМНОЕ спасибо за помощь! Вы мне помогали с сопровождением курсовых работ на протяжении всего срока моего обучения. Без Вашего участия мне было бы в сто раз труднее, ведь я работаю и времени на сопровождение курсовых и диплома всегда катастрофически не хватало. Так что в том, что я закончила этот университет есть большая доля и вашего участия. Ещё раз огромное Вам за это спасибо! Будьте счастливы и удачи Вам! При случае, буду рекомендовать Вас своим знакомым, кому понадобятся подобные услуги ;-)
