    • The present invention is directed generally to protecting cells, tissues and organs against the damaging effects of ionizing or other damaging agents associated with radiation or chemotherapy, or degenerative diseases or processes of various organs that elicit the production of free radicals or oxidants such as peroxides, superoxide anions, hydroxyl radicals or nitric oxides, or heavy metal cations. More particularly, the present invention is concerned with methoxypolyethylene glycol thioester chelate methyl esters that are useful as protectors against tissue damage by penetrating the cell membrane to remove electrons from free radical oxidants and remove heavy metals that may react with peroxides to produce the reactive hydroxyl radical, or remove Ca++ that may be released from organelles. These chelate esters will also have utility in reducing intraocular pressure in glaucoma patients.

    • Novel C3-C19 alkyl- and aryl-thiotrifluoroacetates are provided which have the structure [Formula (I)], wherein Q is C9-C19 alkyl or aryl, and are useful protecting agents for the amino or hydroxy functional groups of amines, amino acids or primary or secondary alcohols or amino alcohols to enable formation of amide bonds in peptides or proteins which are useful as screening agents, pharmaceuticals and cosmetics. A process for preparing C3-C19 alkyl- and aryl-thiotrifluoroacetates is also provided wherein a C3-C19 alkylthiol or arylthiol is treated with trifluoroacetic anhydride (TFAA) in the presence of organic base such as pyridine, a solvent such as dichloromethane (DCM) and dimethylaminopyridine (DMAP) as a catalyst to form the desired C3-C19 alkyl- or aryl-thiotrifluoroacetate. In addition, a process for protecting a primary or secondary amino group or a primary or secondary hydroxyl group or an amino alcohol with a trifluoroacetyl protecting group is provided wherein a primary or secondary amine, amino acid, a primary or secondary alcohol or an amino alcohol is treated with a C3 to C19 alkyl- or aryl-thiotrifluoroacetate in basic aqueous solution.

    • In recognition of the need to develop novel therapeutic agents, the present invention provides novel histone deacetylase inhibitors. These compounds include an ester bond making them sensitive to deactivation by esterases. Therefore, these compounds are particularly useful in the treatment of skin disorders. When the compounds reaches the bloodstream, an esterase or an enzyme with esterase activity cleaves the compound into biologically inactive fragments or fragments with greatly reduced activity Ideally these degradation products exhibit a short serum and/or systemic half-life and are eliminated rapidly. These compounds and pharmaceutical compositions thereof are particularly useful in treating cutaneous T-cell lymphoma, neurofibromatosis, psoriasis, hair loss, skin pigmentation, and dermatitis, for exmaple. The present invention also provides methods for preparing compounds of the invention and intermediates thereto.
    • 鉴于需要开发新的治疗剂,本发明提供了新的组蛋白脱乙酰酶抑制剂。 这些化合物包括酯键,使它们对酯酶的失活敏感。 因此,这些化合物特别可用于治疗皮肤病。 当化合物达到血流时,酯酶或具有酯酶活性的酶将化合物切割成具有大大降低的活性的生物活性片段或片段。理想地,这些降解产物表现出短的血清和/或全身半衰期并被快速消除。 这些化合物及其药物组合物特别可用于治疗皮肤T细胞淋巴瘤,神经纤维瘤病,牛皮癣,脱发,皮肤色素沉着和皮炎。 本发明还提供了制备本发明化合物及其中间体的方法。
