Heterocyclic compounds containing a pyrimidine nucleus are of special interests due to their applications in medicinal chemistry as they are the basic skeleton of several bioactive compounds such as antifungal, antibacterial, antitumor and antitubercular. As a part of our research in the synthesis of pyrimidine derivatives containing biological activities, some new tetrahydropyrimidine derivati...
چکیده زمینه و هدف: با توجه به ایجاد مقاومت و عوارض جانبی دربیماران با مصرف داروهای شیمیایی واهمیت گیاهان دارویی هدف از این تحقیق بررسی اثرات ضد باکتریایی عصاره ی متانولی گیاه انجبار (polygonum bistorta) بر باکتری های اشریشیاکلی(atcc 15224)، سودوموناس آئروژینوزا (atcc 25619)، باسیلوس سوبتیلیس (atcc 6633) واستافیلوکوکوس اورئوس (atcc 25923)بود. روش بررسی: عصاره متانولی از گیاه تهیه شده و اثر ضد می...
MIC and disk diffusion quality control (QC) ranges were established for two new pleuromutilin antimicrobials (BC-3205 and BC-3781) in an eight-laboratory study performed according to Clinical and Laboratory Standards Institute M23-A3 guidelines. Staphylococcus aureus ATCC 29213 and 25923, Streptococcus pneumoniae ATCC 49619, and Haemophilus influenzae ATCC 4927 strains were evaluated. The propo...
Compounds AT2433-A1 (A1), AT2433-A2 (A2), AT2433-B1 (B1), and AT2433-B2 (B2) were isolated from the cultured broth of Actinomadura melliaura sp. nov. (SCC 1655). Structurally these materials are closely related to rebeccamycin (1), an indolocarbazole antitumor antibiotic. A1, A2, B1, and B2 were active against Staphylococcus aureus A9537, Streptococcus faecalis A20688, Streptococcus faecium (AT...
Abstract Background and Objective: Because of increased resistance to antibiotics, side effects of chemical drugs and importance of medicinal plants, we aimed to assess the antibacterial effects of methanolic extract of the Polygonumbistorta plant on the E. coli (ATCC 15224), Ps. aeruginosa (ATCC 25619), B. subtilis (ATCC 6633) and Stap. Aureus (ATCC 25923). Material and Methods: After preparin...
Propionic acid (PA) is an important chemical building block and is widely applied for organic synthesis, food, feedstuff, and pharmaceuticals. To date, the strains that can efficiently produce PA have included Propionibacterium thoenii, P. freudenreichii, and P. acidipropionici. In this report, we show that P. jensenii ATCC 4868 is also able to produce PA in much higher yields than the previous...
Screening of a bacterial artificial chromosome (BAC) library containing metagenomic DNA from human plaque and saliva allowed the isolation of four clones producing antimicrobial activity. Three of these were pigmented and encoded homologues of glutamyl-tRNA reductase (GluTR), an enzyme involved in the C5 pathway leading to tetrapyrole synthesis, and one clone had antibacterial activity with no ...
Acidithiobacillus ferrooxidans strain D3-2, which has a high copper bioleaching activity, was isolated from a low-grade sulfide ore dump in Chile. The amounts of Cu(2+) solubilized from 1% chalcopyrite (CuFeS(2)) concentrate medium (pH 2.5) by A. ferrooxidans strains D3-2, D3-6, and ATCC 23270 and 33020 were 1360, 1080, 650, and 600 mg x l(-1) x 30 d(-1). The iron oxidase activities of D3-2, D3...
