A series of LX2343 derivatives were designed, synthesized and evaluated as neuroprotective agents for Alzheimer'sdisease (AD) in vitro. Most of the compounds displayed potent neuroprotective activities. Especially for compound A6, exhibited a remarkable EC50 value of 0.22 μM. Further investigation demonstrated that compound A6 can significantly reduce Aβ production and increase Aβ clearance, and alleviate

The invention is directed to substituted salicylamide derivatives. Specifically, the invention is directed to compounds according to Formula (I): wherein R, R1 and R2 are as defined herein, or a pharmaceutically acceptable salt thereof. The compounds of the invention are inhibitors of CD73 and can be useful in the treatment of cancer, pre-cancerous syndromes and diseases associated with CD73 inhibition, such as AIDS, the treatment of HIV, autoimmune diseases, infections, atherosclerosis, and ischemia–reperfusion injury. Accordingly, the invention is further directed to pharmaceutical compositions comprising a compound of the invention. The invention is still further directed to methods of inhibiting CD73 activity and treatment of disorders associated therewith using a compound of the invention or a pharmaceutical composition comprising a compound of the invention.

Some pyrrolo[3,2-f]quinazolinones (compounds 4–12), two pyrido[3,2-f]- and two pyrido[2,3-g]quinazolinones (compounds 15, 16 and 22, 23, respectively) were prepared via multistep syntheses. The tricyclic pyrroloquinazolinone nucleus was built starting from 5-aminoindole via a modified reported pathway to form the pyrimidine ring. To synthesize the tricyclic pyridoquinazolinones, new pathways were designed:
Provided herein are compounds of the formula (I):
were R1 is phenyl, R2 is hydrogen, halogen or lower alkyl, X is carbon on nitrogen, and R3 is isoquinoline, -amino, or a 4- to 6-membered heterocycloalkyl ring and pharmaceutically acceptable salts thereof, which are active as DGAT inhibitors and therefore find uses in treatment of diseases associated with abnormal metabolism of triglicerides such as, for example, obesity, type II diabetes mellitus and metabolic syndrome.
