The invention is directed to substituted pyridine derivatives. Specifically, the invention is directed to compounds according to Formula (Iar): (Iar) wherein Yar, X1ar, X2ar, R1ar, R2ar, R3ar, R4ar and R5ar are as defined herein; or a pharmaceutically acceptable salt or prodrug thereof. The compounds of the invention are selective inhibitors of DNMT1 and can be useful in the treatment of cancer, pre-cancerous syndromes, beta hemoglobinopathy disorders, sickle cell disease, sickle cell anemia, and beta thalassemia, and diseases associated with DNMT1 inhibition. 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 DNMT1 activity and treatment of disorders associated therewith using a compound of the invention or a pharmaceutical composition comprising a compound of the invention.
The invention provides small molecule modulators of retinoic acid receptor-related orphan receptors such as RORα, RORβ, or RORγ, of formula
with the variable atoms as defined herein and R1 comprising a hydroxyl- or alkoxyl-substituted fluoroalkyl group. Compounds of the invention can be effective modulators at concentrations ineffective to act on LXR receptors, or on other nuclear receptors, or other biological targets. Methods of modulation the RORs and methods of treating metabolic disorders, immune disorders, cancer, and CNS disorders wherein modulation of an ROR is medically indicated are also provided.
potential target for the discovery of chemosensitizers and anticancer drugs. Amentoflavone (AMF) is reported to be a selective PARP-1 inhibitor. Here, structural modifications and trimming of AMF have led to a series of AMF derivatives (9a–h) and apigenin–piperazine/piperidine hybrids (14a–p, 15a–p, 17a–h, and 19a–f), respectively. Among these compounds, 15l exhibited a potent PARP-1 inhibitory effect

A series of novel 1,4-disubstitutedpiperidine/piperazine derivatives were designed, synthesized and evaluated for their in vitro activities against HIV-1 Bal (R5) infection in CEMX174 5.25M7 cells. A majority of these compounds showed potent anti-HIV-1 activities with IC at nanomolar levels. -(4-Fluoro-benzyl)piperazine analog hydrochloride exhibited potency against HIV-1 activity similar to that of

, A and n have any of the values described in the specification; and pharmaceutically acceptable salts thereof, have activity as inhibitors of PI3K and may thus be used to treat diseases and disorders arising from abnormal cell growth, function or behaviour associated with PI3 kinase such as cancer, immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine disorders and neurological disorders. Processes for synthesizing the compounds are also described.
