    摘要: Bacterial infections, including Methicillin resistant Staphylococcus aureus (MRSA) infections are a major health problem that has created a pressing need for new antibiotics. Pyridazinone, rhodanine, and pyrazolethione compounds effective inhibit the enzymatic activity of sortase A (srtA) found in gram positive bacteria are disclosed. A structure activity relationship (SAR) analysis led to the identification of several pyridazinone and pyrazolethione analogs that inhibit SrtA with IC50 values in the sub-micromolar range. Compounds that inhibit the S. aureus SrtA sortase may function as potent anti-infective agents as this enzyme attaches virulence factors to the cell wall. Many of these molecules also inhibit the sortase enzyme from B. anthracis suggesting that they may be generalized sortase inhibitors.The novel compounds, compositions, uses, formulations, medicaments, articles of manufacture provide improved materials, uses, and treatments useful in combating infectious disorders.

    摘要: A modest (2-5 fold) increase in androgen receptor (AR) mRNA is the only expression change consistently associated with developing resistance to antiandrogen therapy. Increased levels of AR confer resistance to anti-androgens by amplifying signal output from low levels of residual ligand and altering the normal response to antagonists. This invention provides cell based assays for use in the examination of new therapeutic modalities and provides for the design of novel antiandrogen compounds.

    摘要: Methods are provided for preparing all four diastereomers of 2-alkyl-3-hydroxyalkanals, 2-alkyl-3-silyloxyalkanals, and the like, with high enantiocontrol, using non-aldol chemistry. The synthetic methods also provide novel, stereospecific routes to polypropinates and chiral 2-substituted-1,3 diols.
