Reduction of matrix metalloproteinase-9 expression by culture filtrate of Paecilomyces farinosus J3.

The aim of the present study was to investigate the anti-tumor effects of a culture filtrate of Paecilomyces farinosus J3. Various anti-tumor assays using B16 melanoma cells were carried out. Paecilomyces farinosus J3 significantly decreased the wound healing capability, invasiveness and angiogenic activity, which was confirmed by wound healing, human umbilical vein endothelial cell and invasion assays.

CW-270033, a novel pyrrolidinyl-thio carbapenem, has potent antimicrobial activity in vitro and in vivo.

CW-270033, an injectable carbapenem, is a novel, synthesized pyrrolidinyl-thio carbapenem. In the present study, the in-vitro and in-vivo antibacterial activities of CW-270033 against wild-type strains and clinical isolates were compared with those of imipenem and meropenem. CW-270033 was more active than imipenem against Gram-negative (Escherichia coli and Pseudomonas aeruginosa) clinical isolates, but was slightly less active than meropenem.
