RES-529 & the PI3K Pathway First-in-class PI3K/Akt/mTOR pathway inhibitor The PI3K/Akt/mTOR pathway is an important signaling pathway for many cellular functions such as cell proliferation, angiogenesis and vascular permeability Many opportunities for drugs to interfere with its signaling Agents in development affect different targets PI3K inhibitors Akt inhibitors mTOR inhibitors These agents are believed to be limited by feedback loops within the pathway RES-529 is a novel approach to inhibition of the PI3K pathway. Rather than interfering with signaling via specific receptors (e.g. PI3K, Akt, mTOR) it interferes with the molecular components which make up TORC1 and TORC2 preventing these complexes from generating and potentiating signaling within the pathway.

 


GRAPHIC

RES-529 Mechanism of Action RES-529 RES-529 RES-529 interferes with the molecular components of TORC1 and TORC2 preventing these complexes from generating and potentiating signaling and thereby interferes with the activities of the PI3K/Akt/mTOR pathway: translation, cell growth, ribosome biogenesis, metabolism, proliferation, and authophagy

RES-440: Adult Male Syrian Golden Hamsters as a Model for Antiandrogen Activity In Vivo and ability to assess local vs. systemic activity The arrows in this image show the location of the flank glands, one of the unique anatomic characteristics of Syrian hamsters. The flank glands are composed of sebaceous glands, terminal hairs (indicated by the arrow), and pigment cells. Male secretions are produced in response to androgens and are used to mark territory. Topically, Flutamide significant reduced both treated and untreated flank organs as well as reducing the size of androgen-sensitive internal organs. Once-daily RES-440 treatment applied to the right flank organ for 21 days (n =6). Peak effect observed between Days 7-10 and remained through Day 21 Unlike Flutamide at these doses, no decreases of the untreated flank organ were observed.
