化合物11的抗菌谱最广，抗真菌活性最高，对新型隐球菌、白色念珠菌、羊毛状小孢子菌和红色毛癣菌的抗菌活性比酮康唑高，有进一步开发的价值。

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。

Results showed that, pyrolin had obvious action on two species of fungi, and the antifungal effect was positively correlative with concentration. The EC50 was 0.4076 mg/mL and 0.4626 mg/mL respectively after cultured 3 days. The main antifungal period was the fast growth period of fungi, and lead to it lag behind. Observation under SEM revealed that pyrolin caused a series of marked morphological and structural alterations of hyphal. These changes included mutual adhesion of mycelium, the hyphal was irregular in diameter, local denting, some of mycelium was broken, disruption of cell wall, outbreaking of inner cytoplast, and the empty cavity appeared. As a result, pyrolin restrained the growth of these fungi.

结果表明，鹿蹄草素对上述两种真菌均具有明显的抑制作用，抑菌效果与浓度呈正相关，培养3d时的EC50分别为0.4076、0.4626 mg/mL；抑菌时期主要是在真菌的快速生长期，使其快速生长期滞后；扫描电镜显示，鹿蹄草素作用下菌体形态发生异常变化，表现为菌丝体之间相互粘连，菌丝粗细不均匀，细胞壁破裂，局部凹陷，部分菌丝断裂，大量内容物外溢，出现空腔等现象，从而发挥其抑菌作用。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.
