The present application provides novel quinazolines and azaquinazolines and pharmaceutically acceptable salts thereof. Also provided are methods for preparing these compounds. These compounds are useful in for co-regulating RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways by administering a therapeutically effective amount of one or more of the compounds of formula (I), wherein X, Y, T and R4, and R6 to R8' are defined herein, to a patient. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways. A variety of conditions can be treated using these compounds and include diseases which are characterized by abnormal cellular proliferation. In one embodiment/ the disease is cancer.

effective therapies. The RGD (Arg‐Gly‐Asp) integrin αvβ1 was recently investigated for its role in fibrotic disease, and thus warrants therapeutic targeting. Herein we describe the identification of non‐RGD hit small‐moleculeαvβ1inhibitors. We show that αvβ1 activity is embedded in a range of published α4β1 (VLA‐4) ligands; we also demonstrate how a non‐RGD integrin inhibitor (of α4β1 in this case) was

The present invention aims to provide a novel low-molecular-weight compound exhibiting an orexin receptor agonist activity and expected to be useful as a prophylactic or therapeutic agent for narcolepsy and the like. The present invention provides a compound represented by the formula (I):
wherein each symbol is as defined in the description, or a pharmaceutically acceptable acid addition salt thereof, which has an orexin receptor agonist activity, and an orexin receptor agonist containing the compound or a pharmaceutically acceptable acid addition salt thereof.
Novel urea derivatives of the formula ##STR1## wherein R and R.sub.1 are individually selected from the group consisting of hydrogen, chlorine, bromine, nitro, trifluoromethyl, lower alkyl of 1 to 6 carbon atoms and lower alkoxy of 1 to 6 carbon atoms, n is 0 or 1, X is selected from the group consisting of lower alkyl of 1 to 6 carbon atoms optionally substituted with halogen and a nitrogen heterocyclic optionally containing 1 or more other heteroatoms, Y is selected from the group consisting of hydrogen, alkyl of 1 to 4 carbon atoms and S--Z wherein Z is a nitrogen heterocyclic optionally containing 1 or more other heteroatoms and the dotted lines indicate that the compound of formula I may contain no oxygen bound to the sulfur atom or may be in sulfoxide or sulfonyl form which are useful as herbicides and thereon preparation.
gold‐catalyzed nitrogenation of alkynes for the synthesis of carbamides and amino tetrazoles through CC and CCbondcleavages is described. A diverse set of functionalized carbamide and amino tetrazole derivatives were selectively constructed under mild conditions. The chemoselectivity can be easily switched by the selection of the acid additives. The reaction is characterized by its broad substrate scope
