二苯砜(4,4’-二氨基二苯砜,DDS)已广泛作为麻风病的治疗药;然而用二苯砜治疗数年后,在麻风结节组织内仍存在有活力的麻风杆菌。DDS在其它的杆菌内能抑制叶酸的合成,但它对麻风的作用机理尚不清楚。体外试验结果指出,DDS不能穿透麻风分支杆菌。可制备一种抗菌剂以渗透它的靶体来增强其战斗力。而且证实邻-二苯酚氧化酶 Diphenylsulfone (4,4’-diaminodiphenylsulfone, DDS) has been widely used as a therapeutic drug for leprosy; however, after several years of treatment with diphenylsulfone, there is still viable leprosy in the nodules of leprosy. DDS inhibits folic acid synthesis in other bacilli, but its mechanism of action on leprosy is unclear. In vitro test results indicate that DDS can not penetrate Mycobacterium leprae. An antibacterial agent can be prepared to penetrate its target body to enhance its combat effectiveness. And confirmed o-diphenol oxidase
