One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 738-70-5, Name is Trimethoprim, formurla is C14H18N4O3. In a document, author is Fang, Zhuangjie, introducing its new discovery. HPLC of Formula: C14H18N4O3.
A new uridine derivative and a new indole derivative from the coral-associated actinomycete Pseudonocardia sp. SCSIO 11457
A new uridine derivative 11457A (1), and a new indole derivative 11457B (2), together with a known compound 1H-indole-2-carbaldehyde (3), were characterized from the fermentation broth of the actinomycete Pseudonocardia sp. SCSIO 11457, an isolate associated with the scleractinian coral Galaxea fascicularis. Upon detailed spectroscopic analysis, 11457A (1) was identified as a uridine analog, and 11457B (2) was elucidated as an indole derivative 2-hydroxy-1-(1H-indol-2-yl)pentane-1,4-dione. Biological evaluation indicated that none of compounds 1-3 showed antibacterial activities against pathogenic bacteria and cytotoxic activities against human cancer cell lines. [GRAPHICS] .
