Streptomyces strain 24# was isolated from our lab to produce secondary metabolites which could strongly antibiotic to 30 plant pathogenic fungi, such as Helminthosporium sorokinum, fusarium graminearum Schw., Valsa mali, etc.

本实验室通过对一株产生抗真菌活性物质的链霉菌24#抗菌谱的测定，发现其对30余种植物病原真菌有显著拮抗作用，其次生代谢产物对病菌菌丝有断裂、溶壁、缢缩等致畸效应。

The Arabidopsis CYP81F2 gene encodes a P450 monooxygenase that is essential for the pathogen-induced accumulation of 4-methoxyindol-3-ylmethyl glucosinolate, which in turn is activated by the atypical PEN2 myrosinase (a type of β-thioglucoside glucohydrolase) for antifungal defense.

拟南芥CYP81F2基因能都编码一种P450单加氧酶，这对4甲氧基-3二甲胺基芥子油甙的病原体诱导积累物是十分重要的。反过来，它也能被非典型PEN2黑芥子酶激活，以产生抗真菌的防御作用。

New antifungal agents have been developed over the past years based on the discovery of many new target sites of Candida albicands. For example, Echinocandins, aiming at the cell wall of Candida albicands, showed strong antifungal activities to fluconazole resistant candidas and fungal biofilm. Moreover, because β-glucan synthase does not exist on the cell membrane of mammalian cells, Echinocandins has a low toxicity and a promising clinical future. Though the mechanism of Histatin is not clear, it has strong activity not only on candida resistant of polyene and azole, but also to Candida parapsilosis, Candida krusei and Cry ptococcus neoformans. Berberine and Ocimum gratissimum L. were also found to have prominent anti-fungi activities.

近年来相继提出了许多抗白念珠菌药物作用的新靶点并成功开发出一些活性强大，疗效确切的抗真菌药，如以真菌细胞壁为靶点开发出棘白菌素类药物卡泊芬净、米卡芬净等，该类药物主要抑制β-葡聚糖合成酶，体外对氟康唑耐药的念珠菌属及真菌生物被膜表现出强大的抗菌活性，又由于β-葡聚糖合成酶在哺乳类动物细胞内不存在，故具有高效低毒的临床效果，是一极具前途的新型抗真菌药；以真菌细胞膜为靶点开发出Histatin类药物，虽然作用机制目前还不完全明了，但其作用不同于临床常用的多烯类和氮唑类，并已经发现Histatin5对两性霉素B和氮唑类耐药的念珠菌有效，并且对非白念珠菌如光滑念珠菌、克柔氏念株菌、隐球菌等也有杀灭作用；通过对植物药物的研究发现黄连素和丁香罗勒Ocimum gratissimum L。

The current antifungal agents used in clinics usually have severe side-effects, it is necessary to seek for new antifungal agents with known or new mechanisms. China has abundant resources in traditional Chinese medicine, therefore exploition of new antifungal agents therefrom is a feasible way.We have screened antifungal activities of 14 ethanolic extracts from traditional Chinese medicines and 21 natural products by using Saccharomyces cerevisiae GL7 and Prototheca wickerhamii as the model microoranganisms. Among the TCMs tested, Cortex Phellodendri, Flos Caryophylli, Fructus Mume, Rhizoma Coptidis and Radix Sophorae tonkinensis showed high antifungal activity. This study layed certain foundation for the development of new antifungal agents.
