源起于发霉甜苜蓿,脱胎于生化实验室,华法林先生起初作为一种强力灭鼠毒药大杀四方。然而,在进入医药领域的道路上,他却因毒药的身份标签和种种流言而饱受质疑和反对。科学家们揭示了华法林抗凝血的机制,并证明了华法林抗凝治疗对患者的益处。从此,华法林先生以及他的衍生物们成为了抗凝治疗和防治鼠害的前线战士。

Five novel complexes [Co2(BCTA)(H2O)4]n (1), [Co2(BCTA)(Phen)2(H2O)2] (2), [Co2(BCTA)(Bipy)2(H2O)2] (3), [Cu2(BCTA)(Bipy)2(H2O)2]n (4), and [Cd2(BCTA)(Bipy)2(H2O)2]n (5) (H4BCTA=2,5-bis(carboxymethoxy)terephthalic acid, Phen=1, 10-phenanthroline, Bipy=2, 2′-bipyridine) were synthesized by solvothermal condition. All complexes were structurally characterized by infrared spectroscopy, elemental analysis, thermogravimetric analysis, and single-crystal X-ray diffraction. Complexes 2 and 3 have zero-dimensional structures, complex 5 has a 1D banded structure, and complexes 1 and 4 have 2D network structures. Hirshfeld surface analysis of complexes 1-5 was performed, and antifungal activities of the complexes were investigated. Complex 5 exhibited super-strong antifungal activity against seven pathogenic fungi, with all inhibitory rates reaching 100%.
