一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Penicillic acid is synthesized by a large number of fungi, such as P. puberulum, Penicillium stoloniferum, P. eye/opium Penicillium martensii, Penicillium thomii. The synthesis of this secondary metabolite has little or no taxonomic significance [1].
In vitro: The compound was active primarily against gram-negative bacteria, and it was also active against some gram-positive species. It showed limited antihelminthic properties but did affect the growth of oat seed coleoptiles by interference with the respiratory process. Penicillic acid has proven to be too toxic for use in therapy [1]. Penicillic acid (80 μM) inhibited bacterial quorum sensing communication in P. aeruginosa by selectively repressing various virulence factor and other quorum sensing-regulated genes [2]. In Burkitt’s lymphoma Raji cells, penicillic acid exihibited an inhibitory effect on Fas-mediated apoptosis at 100-200 μM by targeting caspase-8 activity [3].
In vivo: The LDso (subcutaneous injection) for mice is 100 mg/kg. Subcutaneous injection of 1.0 mg/dose twice weekly produced transplantable tumors after 64 weeks in all rats surviving treatment. In addition, a dose at 0.1 mg initiated tumor development [1].
