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.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In a patent, Application of 135034-10-5, molecular formula is C4H2ClIN2, introducing its new discovery. Application of 135034-10-5

Abstract Despite recent success there remains a high therapeutic need for the development of drugs targeting diseases associated with the metabolic syndrome. As part of our search for safe and effective MCH-R1 antagonists for the treatment of obesity, a series of 3,6-disubstituted pyridazines was evaluated. During optimization several issues of the initial lead structures had to be resolved, such as selectivity over related GPCRs, inhibition of the hERG channel as well as the potential to induce phospholipidosis. Utilizing property-based design, we could demonstrate that all parameters can significantly be improved by consequently increasing the polarity of the compounds. By this strategy, we succeeded in identifying potent and orally available MCH-R1 antagonists with good selectivity over M1 and 5-HT2A and an improved safety profile with respect to hERG inhibition and phospholipidosis.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst does not appear in the overall stoichiometry of the reaction it catalyzes. “Application of 135034-10-5
