根据假定:一个有抗神經性病毒活性的药物应具有亲神經性,特別是向脑神經性。将憎水性的烃基及亲水性的氨基引入硫代巴比吐酸形成5烃基4氨基2硫脲嘧啶,并試驗了这类化合物对日本B型脑炎病毒中山株的作用。試驗結果指出5(2-異丁基4甲基戊基)4氨基2硫脲嘧啶及5-(2-乙基癸基)4氨基
It is hypothesized that a drug that has anti-neuroviral activity should be neurotropic, especially neuropathic. Hydrophobic hydrocarbon groups and hydrophilic amino groups were introduced into thiobarbituric acid to form 5-hydrocarbyl 4-amino-2-thiouracil. The effects of these compounds on Japanese B-type encephalitis isolates were tested. The test results indicate that 5 (2-isobutyl 4 methylpentyl) 4 amino 2 thiouracil and 5- (2-ethyldecyl) 4 amino
