摘要:
Provided are a compound including a cleavable linker, a use thereof, and an intermediate compound for preparing the same, and more particularly, the compound including a cleavable linker of the present invention may include an active agent (for example, a drug, a toxin, a ligand, a probe for detection, etc.) having a specific function or activity, a SO 2 functional group which is capable of selectively releasing the active agent, and a functional group which triggers a chemical reaction, a physicochemical reaction and/or a biological reaction by external stimulation, and may further include a ligand (for example, oligopeptide, polypeptide, antibody, etc.) having binding specificity for a desired target receptor.
摘要:
Cinnamic acid-based oligomers and therapeutic uses thereof are provided. The oligomers are used as anti-inflammation agents, inhibitors of elastase and anti-oxidants, and in some cases (e.g. the treatment of lung disorders such as lung cancer) all three activities are simultaneously beneficial. Subsets of the oligomers (e.g. ß-O4 and ß-5 trimers and tetramers) are used as anticoagulants.
摘要:
The present invention comprises small molecular weight, non-peptidic inhibitors of formula (I) and (II) of Protein Tyrosine Phosphatase 1 (PTP1) which are useful for the treatment and/or prevention of Non-Insulin Dependent Diabetes Mellitus (NIDDM).
