AbstractN‐Sulfonylimines of cycloalk‐2‐enones are well‐suited for the enantioselective rhodium(I)/binap‐catalyzed 1,4‐additions of arylzinc halides. The cyclic enamides, obtained after quenching, are sensitive towards chromatography, but can undergo diastereoselective reductions to furnish cis‐ or trans‐3‐arylcycloalkylamines with five‐ to seven‐membered rings. The 1,4‐addition is not influenced by a methyl group at C‐5 of six‐membered rings, providing further configurational options. 3‐Arylcycloalkylamines are subunits in a number of bioactive substances and can also be oxidatively transformed into cyclic γ‐amino acids.magnified image
Provided are a series of novel pyridine or pyrimidine derivatives which inhibit CDK9 and may be useful for the treatment of hyperproliferative diseases. In particular the compounds are of use in the treatment of proliferative disease such as cancer including hematological malignancies such as acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia, diffuse large B cell lymphoma, Burkitt's lymphoma, follicular lymphoma and solid tumors such as breast cancer, lung cancer, neuroblastoma and colon cancer.

In this paper, we applied an innovative nuclear magnetic resonance (NMR)-guided screening and liganddesignapproach, named focused high-throughput screening by NMR (fHTS by NMR), to derive potent, low-molecular-weight ligands capable of mimicking interactions elicited by ephrin ligands on the receptor tyrosine kinase EphA4. The agents bind with nanomolar affinity, trigger receptor activation in cellular

export is facilitated by Mfsd2b and spinster homologue 2 (Spns2). While mouse genetic studies suggest that Spns2 functions to maintain lymph S1P, Spns2inhibitors are necessary to understand its biology and to learn whether Spns2 is a viable drug target. Herein, we report a structure–activity relationship study that identified the first Spns2inhibitor 16d (SLF1081851). In vitro studies in HeLa cells demonstrated

Provided are a series of novel pyridine or pyrimidine derivatives of Formula (I) which inhibit CDK9 and may be useful for the treatment of hyperproliferative diseases. In particular the compounds are of use in the treatment of proliferative diseases such as cancer including hematological malignancies such as acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia, diffuse large B cell lymphoma, Burkitt's lymphoma, follicular lymphoma and solid tumors such as breast cancer, lung cancer, neuroblastoma and colon cancer. A is C(R5) or N; R5 is H, C1-3alkyl, CN or halogen; R2 is optionally substituted 3-7 membered heterocycloalkyl or 3-7 membered cycloalkyl; R4 is (A) or (B) wherein X and Y together with the atoms to which they are attached form an optionally substituted, saturated or partially saturated 5 to 7 membered heterocycloalkyl ring which, in addition to the bridge nitrogen, may contain one or two heteroatoms selected from N, O, and S; J is N or CR11; and R11 is H or C1-3alkyl.
The invention provides a compound of Formula (Ia), (Ib), (Ic), (Id), (Ie), (If), (Ig), (Ih), (Ii), (Ij), (Ik), or (Il) as defined herein, pharmaceutically acceptable salts, pro-drugs, biologically active metabolites, stereoisomers and isomers thereof wherein the variable are defined herein. The compounds of the invention are useful for treating immunological and oncological conditions.
