    • A method for introducing a mutation into a desired site in Herpes Simplex Virus Type 1 uses a set of starting vectors, where each starting vector has a fragment of the substantially complete HSV-1 genome and also DNA which overlaps with a sequential genomic fragment contained in other starting vectors, so that upon co-transfection of a host cell, replication of viral DNA, and recombination, a mutated replicable virus is formed. The starting vector containing a gene which is to be mutated is replaced by a replacement vectors. The replacement vectors contain a copy of the mutated gene and overlapping DNA, and genomic DNA which was present in the starting vector. A host cell is transformed with the replacement vectors and the remaining starting vectors under conditions allowing replication of viral DNA and recombination to form a replicating mutated virus. In preferred embodiments, the protease gene is mutated.
    • 将突变引入单克隆单纯疱疹病毒1型中的所需位点的方法使用一组起始载体,其中每个起始载体具有基本上完整的HSV-1基因组的片段,以及与包含在其中的连续基因组片段重叠的DNA 其他起始载体,使得当共转染宿主细胞时,病毒DNA的复制和重组,形成突变的可复制病毒。 含有待突变的基因的起始载体被替换载体所取代。 替换载体含有突变基因和重叠DNA的拷贝,以及起始载体中存在的基因组DNA。 在允许复制病毒DNA并重组以形成复制突变病毒的条件下,用置换载体和剩余起始载体转化宿主细胞。 在优选的实施方案中,蛋白酶基因被突变。

    • The abuse potential of a bioavailable drug such as an opiate analgesic agent is reduced and its duration of action is extended by converting it to a poorly absorbed ester prodrug or other prodrug derivative prior to formulation. Unlike many existing sustained release formulations of active pharmaceutical agents wherein an active pharmaceutical agent can be released by chewing, crushing, or otherwise breaking tablets or capsule beads containing the active pharmaceutical agent, such mechanical processing of tablets or capsule beads containing a prodrug of this invention neither releases the active drug nor compromises the controlled conversion of prodrug to drug. Moreover, tablets and capsule beads containing prodrugs of this invention or other drugs can be formulated with a sufficient amount of a thickening agent such as hydroxypropylmethylcellulose or carboxymethylcellulose to impede inappropriate intravenous and nasal administration of formulations that are not indicated for these modes of administration.
    • 降低生物可利用药物如鸦片止痛剂的滥用潜力,并且通过在制剂前将其转化为不良吸收的酯前药或其它前药衍生物来延长其作用时间。 与活性药物的许多现有持续释放制剂不同,其中通过咀嚼,破碎或以其它方式破坏含有活性药剂的片剂或胶囊珠可以释放活性药剂,这种包含本发明前药的片剂或胶囊珠粒的机械加工 既不释放活性药物也不妥协药物对药物的受控转化。 此外,含有本发明前药或其他药物的片剂和胶囊珠可以用足量的增稠剂如羟丙基甲基纤维素或羧甲基纤维素配制,以阻止对这些给药模式未注明的制剂的不适当的静脉内和鼻内施用。
