  • Publication number: 20240083846
    Abstract: The present invention relates to novel SMAC mimetic peptidomimetics useful for the treatment of proliferative diseases including cancer in mammals The novel SMAC mimetics are prepared by incorporating (2S,5R)-5-(5-methylfuran-2-yl)pyrrolidine-2-carboxylic acid, a novel unnatural amino acid that imparts exclusively trans amide bond geometry favourable for target protein binding. Here, the novel SMAC mimetic molecule(s) not only show its efficacy in varied cancer types but also demonstrate in vitro and in vivo efficacy against therapy resistant cancer as a single agent. The novel SMAC mimetics disclosed in the present invention binds to BIR-2 and BIR-3 domains of the XIAP and exhibit high anti-proliferative activity against variety of mammalian cancer cell lines that include but not limited to chemotherapy and TRAIL resistant cell lines.

  • Patent number: 10599718
    Abstract: Techniques for mapping from one or more source information sets to one or more target information sets are provided. Mapping ontologies associate a first declarative expression with a first information set from which to read first information, and a second declarative expression with a second information set to which second information determined based upon the read first information is written. A mapping graph having a nodes arranged according to an execution flow for obtaining the one or more target information sets is generated, at least some of these nodes representing respective ones of the mapping ontologies. The one or more target information sets are generated, each including information determined from the one or more source information sets, by traversing the mapping graph according to the execution flow. Each of the first and second declarative expressions may be associated with a mapping resolver for accessing one or more information sets.
