Designing Anti-inflammatory Drugs from Parasitic Worms: A Synthetic Small Molecule Analogue of the Acanthocheilonema viteae Product ES-62 Prevents Development of Collagen-Induced Arthritis
摘要:
In spite of increasing evidence that parasitic worms may protect humans from developing allergic and autoimmune diseases and the continuing identification of defined helminth-derived immunomodulatory molecules, to date no new anti-inflammatory drugs have been developed from these organisms. We have approached this matter in a novel manner by synthesizing a library of drug-like small molecules based upon phosphorylcholine, the active moiety of the anti-inflammatory Acanthocheilonema viteae product, ES-62, which as an immunogenic protein is unsuitable for use as a drug. Following preliminary in vitro screening for inhibitory effects responses, a sulfone-containing phosphorylcholine analogue (11a) was selected for testing in collagen-induced arthritis (CIA). Testing revealed that 11a was as effective as ES-62 in protecting DBA/1 mice from developing CIA and mirrored its mechanism of action in downregulating the TLR/IL-1R transducer, MyD88. 11a is thus a novel prototype for anti-inflammatory drug development. on relevant macrophage cytokine an in vivo model of inflammation,

The invention relates to chemical compounds of the formula (I), or a pharmaceutically acceptable salt thereof, which possess inhibitory activity against the spindle checkpoint kinase: Tyrosine Threonine Kinase (TTK)/monopolar spindle 1 (Mpsl) and are accordingly useful for their anti-cancer effect in a warm-blooded animal such as man. The invention also relates to processes for the manufacture of said chemical compounds, to pharmaceutical compositions containing them, and to their use in the manufacture of a medicament for the treatment of conditions mediated by TTK/Mpsl, for use either alone or in combination with other anti-pro liferative agents.
