چکیده
In addition to the known mutisicoumarin A, the aerial parts of the shrub Mutisia friesiana afforded five new methylphenones, two new 5-methylcoumarins and a new related chromone. Their structures were elucidated by spectroscopic methods 13C NMR data for mutisicoumarin A are reported for the first time. Mutisiphenones A and B and mutisicoumarin A showed antifungal activity against the phytopathogenic fungus Cladosporium cucumerinum.

5-methylcoumaranones from Mutisia friesiana and their bioactivity.
In addition to the known mutisicoumaranones A (1) and B (2), the methanolic extract of the aerial parts of the shrub Mutisia friesiana afforded two new 5-methylcoumaranones, mutisicoumaranones C (3) and D (4). Their structures were elucidated by spectroscopic methods. (13)C NMR data for mutisicoumaranones A and B are reported for the first time. All compounds showed antifungal activity against ...
متن کاملSynthesis of Novel 4-Methylcoumarins and Comparative Specificities of Substituted Derivatives for Acetoxy Drug: Protein Transacetylase
Our laboratory has been credited for the discovery of a unique membrane bound enzyme termed Acetoxy Drug: Protein Transacetylase (TAase) catalyzing the transfer of acetyl group from polyphenolic peracetates (PA) to certain functional proteins resulting in the modulation of their catalytic activity. In this report, we have synthesized eight novel 4-methylcoumarins and demonstrated the comparison...

Reaction of aryl methyl ketone with isatin in the presence of a base afforded 2- arylquinoline-4-carboxylic acid (3). Reaction of diazomethane with compound 3 yielded the ester 4. Compound 5 was prepared from the reaction of N, N'-dialkylethyl (or propyl) arnine with 4. Addition of hydrazine hydrate to compound 4a gave 2- (2- pyridyl) quinoline-4-carboxylic acid hydrazide (6). Reaction of l...
متن کاملBiological Evaluation of Heterocycle Moiety of Some Novel azoles Derivatives as Antibacterial and Antifungal potential Agents
Background & Objective: Azole nucleuses are very important part of antimicrobial, analgesic and anti-inflammatory drugs. The azole class of compounds is the most popular among the antibacterial and antifungal classes because of its lower toxicity, higher efficacy and a broad spectrum of activity. Today, Efforts have focused on the development of new, less toxic and more efficacious antifungal a...
متن کاملSynthesis and evaluation of the antifungal effects of [5-aryl-[1, 3, 4] oxadiazole-2-yl] phenyl-methanol
Introduction: Nowadays the drug resistance outbreak in fungi is considered a serious threat to the health of human societies. Oxadiazole derivatives that are high biologically applicable can be a good alternative to common anti-fungal drugs. The purpose of this study was to evaluate the anti-fungal properties of new derivatives synthesized of oxadiazole and compare them with common anti-fungal ...
