    • The present invention is directed to a procedure for enhancing the enzyme-dependent readout of diagnostic assays using specially prepared liposomes.
      Microgenic's CEDIA assay for digoxin was employed as an illustrative example of the present invention. The magnitude of signal was only 25 mA/min/ng digoxin/ml for the unamplified assay, while the signal magnitude for the amplified (i.e., liposome-enhanced) assay was 1,000 mA/min/ng digoxin/mL, i.e., a 40-fold amplification.
      Stable liposomes were prepared with unsaturated PE stabilized with 5 mole percent of ganglioside GM₁. Glucose-6-phosphate dehydrogenase (G6PHD) was entrapped in these unilamellar liposomes in high concentrations. Addition of beta-galactosidase (B-gal) caused rapid (3-5 min.) lysis of liposomes revealing the latent G6PDH activity, due to the enzymatic degalactosylation of MG₁.
      This simple, rapid and homogenous signal amplification procedure will be useful in many enzyme dependent assays, such as ELISA, CEDIA, Gene-probe assays and Immunoliposome assays.
    • 本发明涉及使用特别制备的脂质体来增强诊断测定酶的酶依赖性读出的方法。 作为本发明的说明性实施例,使用了用于地高辛的微生物CEDIA测定。 对于未扩增测定,信号的幅度仅为25mA / min / ng地高辛/ ml,而扩增(即,脂质体增强)测定的信号幅度为1,000mA / min / ng地高辛/ mL,即40 倍放大。 用5摩尔%的神经节苷脂GM1稳定的不饱和PE制备稳定的脂质体。 葡萄糖-6-磷酸脱氢酶(G6PHD)以高浓度包埋在这些单层脂质体中。 加入β-半乳糖苷酶(B-gal)引起脂质体的快速(3-5分钟)裂解,显示由于MG1的酶脱羧基化而引起潜在的G6PDH活性。 这种简单,快速和均匀的信号扩增程序将在许多酶依赖性测定中有用,例如ELISA,CEDIA,基因探针测定和免疫脂质体测定。

    • This invention provides a novel class of androgen receptor targeting agents (ARTA). The agents define a new subclass of compounds which are tissue-selective androgen receptor modulators (SARM), which are useful for oral testosterone replacement therapy, male contraception, maintaining sexual desire in women, treating prostate cancer and imaging prostate cancer. These agents have an unexpected in-vivo activity for an androgenic and anabolic activity of a nonsteroidal ligand for the androgen receptor. These agents may be active alone or in combination with progestins or estrogens. The invention further provides a novel class of nonsteroidal agonist compounds and methods of binding an androgen receptor, modulating spermatogenesis, treating and imaging prostate cancer, and providing hormonal therapy for androgen-dependent conditions.
