    摘要: The present invention relates to a prodrug of 5-azacytidine or 2′-deoxy-5-azacytidine having remarkable stability against cytidine deaminase, a metabolic hydrolyzing enzyme in replacement of current injections (5-azacytidine or 2′-deoxy-5-azacytidine) which are clinically used as therapeutic agents for various myelomas including myelodysplastic syndrome. The present invention provides a compound represented by formula (1), or salt thereof, wherein, R is OR3 or a hydrogen atom, R1, R2, and R3 are each independently hydrogen atom or silyl group represented by formula (2): wherein, R1, R5, and R6 are each independently alkyl group which may have a substituent, aryl group which may have a substituent, or arylalkyl group which may have a substituent, with the provision that R1, R2, and R3 are not hydrogen atom simultaneously.

    摘要: Conjugates are provided which comprise a membrane permeable drug linked to a moiety that is not membrane permeable. Attachment of the moiety that is not membrane permeable prevents the drug from crossing cell membranes and entering cells. However, exposure to light either i) breaks the linkage, releasing the drug and allowing it to enter cells; or ii) converts the non-membrane permeable moiety to a membrane permeable form, allowing the entire conjugate to enter the cell, where the drug is released from the conjugate by cleavage. The membrane permeable drugs are thus delivered to cells at locations of interest, e.g. cancer cells in a tumor, in a temporally and spatially controlled manner.

    摘要: The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of retinoids and retinoid-related compounds, which are capable of crossing biological barriers with high penetration efficiency. The HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

    摘要: The present invention provides compositions and methods for the targeted delivery, release and/or formation of a drug compound at a target site(s) within the body of an individual, such as a diseased and/or inflamed tissue in the body of the individual. These compositions may comprise a halogenated phenol ring cleavably linked to a core structure of a drug compound. Due to the variety of substituents that may be utilized in forming the different types of linkages, numerous examples of drug compounds linked to a halogenated phenol ring are proposed. The present invention further provides compositions comprising halogenated phenol starting compounds that do not undergo cleavage during a dehalogenation reaction to form a drug compound in a targeted tissue when administered to an individual. Methods of administering these non-cleaving compounds are further provided.
