I-Catalyzed Oxidative Cross-Coupling Reaction of Methyl Ketones and 2-(2-Aminophenyl) Benzimidazole: Facile Access to Benzimidazo[1,2-]quinazoline.

A general and efficient iodine-catalyzed metal-free oxidative cross-coupling reaction of methyl ketones with 2-(1-benzo[]imidazol-2-yl)aniline has been established. This is a new synthetic strategy for the synthesis of benzimidazo[1,2-]quinazoline derivatives involving C(sp)-H oxidation, condensation, and cyclization processes.

Effect of methyl salicylate (MeSA), an elicitor on growth, physiology and pathology of resistant and susceptible rice varieties.

Methyl salicylate (MeSA) is a volatile organic compound synthesized from salicylic acid (SA) a plant hormone that helps to fight against plant disease. Seed treatment with MeSA, is an encouraging method to the seed industry to produce more growth and yield. The aim of our study is to find out the growth, development and disease tolerance of rice seed treated with different concentrations of MeSA.

GC-MS analysis of bioactive compounds from the whole plant ethanolic extract of Evolvulus alsinoides (L.) L.

Medicinal plants are at great interest to the researcher in the field of biotechnology, as most of the drug industries depend in medicinal plants for the production of pharmaceutical compounds. Plants are the traditional sources for many chemicals used as pharmaceutical biochemicals, fragrances, food colours and flavours in different countries especially in India. Most herbal medicines and their derivative products were often prepared from crude plant extracts, which comprise a complex mixture of different phytochemical constituents (plant secondary metabolites).

Antioxidant activity and functional group analysis of Evolvulus alsinoides.

Aim: AMany oxidative stress-related diseases occur as a result of the accumulation of free radicals in the body. Free radicals are generated by various endogenous systems, exposure to different physiochemical conditions, or pathological states. A balance between free radicals and antioxidants is necessary for appropriate physiological function.

In vitro free radical scavenging activity of ethanolic extract of the whole plant of Evolvulus alsinoides (L.) L.

Objective: To identify the free radical scavenging activity of ethanolic extract of Evolvulus alsinoides.

Methods: The free radical scavenging activity was evaluated by in vitro methods like reducing power assay, total antioxidant activity, 2,2-diphenyl-1-picrylhydrazyl (DPPH) reduction, superoxide radical scavenging activity, 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS(+)) scavenging activity, hydroxyl radical scavenging assay, and nitric oxide radical scavenging assay, which were studied by using ascorbic acid as standard.

Results: The extract showed significant activities in all antioxidant assays compared with the reference antioxidant ascorbic acid.
