    • Method for inactivating non-enveloped viruses using a viricide-potentiating agent. In a preferred embodiment, the method may be used to inactivate non-enveloped viruses present within a sample of whole blood or a blood product and comprises (a) adding to the blood sample a photoactivatable viricide, such as a psoralen, hypericin, methylene blue, toluidine blue or the like, which, when activated, is effective in inactivating enveloped viruses; (b) adding to the blood sample a viricide-potentiating chemical agent that increases the sensitivity of non-enveloped viruses to the activated viricide; and (c) activating the photoactivatable viricide. Preferably, the viricide-potentiating chemical agent includes a first moiety which possesses an affinity for a component of the non-enveloped virus and a second moiety which includes a lipid tail, the first and second moieties being structurally interrelated so that, when the first moiety becomes associated with a component of the non-enveloped virus, the second moiety penetrates or at least partially surrounds the viral capsid of the non-enveloped virus. Examples of the chemical agent include cationic lipopolyamines, such as dioctadecylamidoglycylspermine.

    • An in vitro method for identifying distinct, first generation, drug-resistant, biologically active, HIV protease mutants that may emerge in vivo in response to a drug targeted thereagainst comprising: (a) preparing, in the presence of the drug, a library of all first-generation mutants of the protease differing therefrom by one to three amino acid substitutions, each of the protease mutants being generated as part of a polyprotein with reverse transcriptase; (b) isolating drug-resistant, biologically-active mutant proteases by assaying for activity of the reverse transcriptase; and (c) identifying the distinct amino acid changes leading to the drug-resistance of the active, mutant proteases so isolated. An in vitro method for evaluating the efficacy of a drug against a biologically active mutant or wild-type form of HIV protease comprising combining the drug and a mutant polyprotein, comprising an inactive HIV protease, HIV reverse transcriptase, and one or more protease cleavage sites, adding biologically-active mutant or wild-type protease, assaying for release of active reverse transcriptase, whereby reverse transcriptase activity indicates that the drug is not efficacious against the mutant or wild-type form of HIV protease tested.
    • 一种体外方法,其用于鉴定可能在其靶向靶向药物的体内可能出现的不同的第一代,耐药性,生物活性的HIV蛋白酶突变体,其包括:(a)在所述药物存在下,制备 所有蛋白酶突变体的所有第一代突变体通过一至三个氨基酸取代基与之不同,每个蛋白酶突变体作为具有逆转录酶的多聚蛋白的一部分产生; (b)通过测定逆转录酶的活性来分离耐药性,生物活性的突变型蛋白酶; 和(c)鉴定导致如此分离的活性突变蛋白酶的耐药性的不同氨基酸变化。 一种用于评估药物对生物活性突变体或野生型形式的HIV蛋白酶的功效的体外方法,包括将药物和突变体多蛋白(包括无活性的HIV蛋白酶,HIV逆转录酶和一个或多个蛋白酶切割位点) ,添加生物活性突变体或野生型蛋白酶,测定活性逆转录酶的释放,由此逆转录酶活性表明该药物对于所测试的HIV蛋白的突变体或野生型形式是无效的。

    • A method of inactivating viral molecules present within a blood sample and compounds for use in same. The method involves adding to a virus-containing blood sample an effective quantity of a compound which both has an affinity for viral nucleic acid and which is activatable to an excited state in which the compound covalently binds viral nucleic acid. After permitting the compound to complex with viral nucleic acid, the compound is raised to its excited state by chemical activation. In a first preferred embodiment, psoralen, hypericin or a derivative of psoralen or hypericin is used as the activatable, viral-inactivating compound, and chemical activation of the compound is effected by the decomposition of a dioxetane proximate to the nucleic acid/compound complex. In a second preferred embodiment, the activatable, viral-inactivating compound is incorporated into a dioxetane molecule, and chemical activation of the compound is effected by decomposition of the dioxetane into a pair of carbonyl compounds.
