  • Publication number: 20150051193
    Abstract: Compounds and methods are provided for the treatment of pathogen infections. In some embodiments, the anti-infective compounds have broad spectrum activity against a variety of infective diseases, where the diseases are caused by pathogens containing a basic amino acid PIP-2 pincer (BAAPP) domain that interacts with phosphatidylinositol 4,5-bisphosphate (PIP-2) to mediate pathogen replication. Also provided are methods of inhibiting a PI4-kinase and methods of inhibiting viral infection. In some embodiments, the compound is a PI4-kinase inhibiting compound that is a 5-aryl-thiazole. The subject compounds may be formulated or provided to a subject in combination with a second anti-infective agent, e.g. interferon, ribivarin, and the like.

  • Patent number: 8748601
    Abstract: Inhibition of protein kinases having one or more cysteine residues within the ATP binding site is effected by contacting the kinase, per se or in a cell or subject, with an inhibitory-effective amount of a compound having a heterocyclic core structure comprised of two or more fused rings containing at least one nitrogen ring atom, and an electrophilic substituent that is capable of reacting with a cysteine residue within the ATP binding site of a kinase. Preferred compounds include certain pyrrolopyrimidines and oxindoles having such an electrophilic substituent and optionally an aromatic or heteroaromatic substituent that is capable of interacting with a threonine or smaller residue located in the gatekeeper position of the kinase. Kinases lacking such cysteine residues may be engineered or modified so that they are capable of being inhibited by such compounds by replacing a valine or other amino acid residue within the ATP binding site by a cysteine residue.
