- Structure-based design of a novel series of potent, selective inhibitors of the class i phosphatidylinositol 3-kinases
-
A highly selective series of inhibitors of the class I phosphatidylinositol 3-kinases (PI3Ks) has been designed and synthesized. Starting from the dual PI3K/mTOR inhibitor 5, a structure-based approach was used to improve potency and selectivity, resulting in the identification of 54 as a potent inhibitor of the class I PI3Ks with excellent selectivity over mTOR, related phosphatidylinositol kinases, and a broad panel of protein kinases. Compound 54 demonstrated a robust PD-PK relationship inhibiting the PI3K/Akt pathway in vivo in a mouse model, and it potently inhibited tumor growth in a U-87 MG xenograft model with an activated PI3K/Akt pathway.

- Process for the preparation of 2-amino-4-chloro-1,3,5-triazines
-
Compounds of the formula (I) or salts thereof are suitable for preparing active substances from the from the class of the aminotriazines of the formula (IV), for example herbicidal active substances. The compounds (I) can be prepared by chlorinating compounds of the formula (II) where, in the formulae, R1, R2, R3 and X are as defined in claim 1 and A and R have the meaning required in the active substances to be prepared, and they can be reacted with amines of the formula A—NH—R to give the active substances.
