    • A method of linking nucleosides with a siloxane bridge comprising reacting a 3'-silylated-5'-protected nucleoside with an unprotected nucleoside is disclosed. The silylated and unprotected nucleosides may be either monomeric nucleosides or the terminal nucleosides of an oligonucleotide or oligonucleotide analog. A method of synthesizing an oligonucleotide analog having siloxane internucleoside linkages is also disclosed. The method of synthesis comprises silylating a 5'-protected nucleoside with a bifunctional silylating reagent to form a 3'-silylated nucleoside, reacting the silylated nucleoside with an unprotected nucleoside in the presence of a base catalyst and repeating these steps to form an oligonucleotide analog. A modified solid phase synthesis method for preparing an oligonucleotide analog having siloxane internucleoside linkages is also disclosed.
    • 公开了将核苷与硅氧烷桥连接的方法,包括使3'-甲硅烷基化-5'-保护的核苷与未保护的核苷反应。 甲硅烷基化和未保护的核苷可以是单体核苷或寡核苷酸或寡核苷酸类似物的末端核苷。 还公开了合成具有硅氧烷核苷间键的寡核苷酸类似物的方法。 合成方法包括用双官能甲硅烷基化试剂甲硅烷基化5'-保护的核苷以形成3'-甲硅烷基化核苷,在碱催化剂存在下使甲硅烷基化的核苷与未保护的核苷反应,并重复这些步骤以形成寡核苷酸类似物 。 还公开了用于制备具有硅氧烷核苷间键的寡核苷酸类似物的改进的固相合成方法。

    • The present invention discloses and claims compositions, methods of treatment, and kits which cause an increase in the time of survival in cancer patients, wherein the cancer: (i) overexpresses thioredoxin or glutaredoxin and/or (ii) exhibits evidence of thioredoxin- or glutaredoxin-mediated resistance to one or more chemotherapeutic interventions. The present invention also discloses and claims methods and kits for the administration of said compositions to properly treat cancer patients. Additionally, the present invention discloses and claims methods and kits for quantitatively determining the level of expression of thioredoxin or glutaredoxin in the cancer cells of a cancer patient, methods of using those determined levels in the initial diagnosis and/or planning of subsequent treatment methodologies for said cancer patient, as well as ascertaining the potential growth “aggressiveness” of the particular cancer and treatment responsiveness of the particular type of cancer. Further, the present invention discloses and claims novel pharmaceutical compositions, methods, and kits used for the treatment of patients with medical conditions and disease where there is the overexpression of thioredoxin and/or glutaredoxin, and wherein this overexpression is associated with deleterious physiological effects in the patients.
