- Synthesis and antibacterial activities of Yanglingmycin analogues
-
The synthesis of Yanglingmycin and its enantiomer, along with eighteen Yanglingmycin analogues is reported. The structures were confirmed mainly by analyses of NMR spectral data. Antibacterial activity assays showed that Yanglingmycin and some of its analogues exhibited significant antibacterial activities against two important agricultural pathogenic bacteria, Ralstonia solanacearum and Pseudomonas syringae pv. actinidiae, with minimum inhibitory concentration (MIC) values ranging from 3.91 to 15.62 μg/mL. The antibacterial activities exhibited by Yanglingmycin and its analogues are promising, suggesting potential in the development of compounds for novel bactericides.

- Compounds and methods for identifying activated platelets
-
The invention is directed to a series of novel compounds, and their pharmaceutically acceptable salts, of the formula STR1 wherein R is C0-6 alkyl substituted with R5 or a mono or polycyclic aromatic or heteroaromatic system comprised of 5 or 6-membered aromatic or heteroaromatic rings that are either unsubstituted or substituted with one or more of R1 and R2 ; R1 and R2 are independently C1-6 alkyl, carboxyl, hydroxyl, azido, nitro, amino, C1-6 alkylamino, C1-6 dialkylamino, arylamino, aryl C1-6 alkylamino, hydroxysulfonyl or arylazo; aryl is a phenyl or naphthyl ring which is unsubstituted or substituted with one or more of R3 and R4 ; R3 and R4 are independently C1-6 alkyl, azido, nitro, amino, C1-6 dialkylamino or hydroxysulfonyl; R5 is STR2 provided that when R is an unsubstituted monocyclic ring, the monocyclic ring is not phenyl or pyridyl. Such compounds are useful as fluorescent probes for identifying antiplatelet agents which selectively bind to activated platelets.
