Paragraph 0094; 0096-0098, (2019/03/20)
PROBLEM TO BE SOLVED: To provide a method for manufacturing optical active secondary alcohol with high optical purity by hydrogenating a substrate carbonyl compound using a ruthenium complex with a specific optical active diphosphine compound and an amine compound of which synthesis is easy as ligands as a catalyst. SOLUTION: The manufacturing method of optical active secondary alcohol including reacting a substrate carbonyl compound (excluding 3-quinuclidinone, a 3-quinuclidinone derivative having a substituent, and ketone having an aromatic hydrocarbon group and a heterocycle) with hydrogen and/or a hydrogen-donating compound in a presence of a ruthenium complex selected from a compound represented by the following general formula (1) RuXYAB (1) [X and Y are same or different, represent a hydrogen atom or an anionic group, A represents optical active diphosphine represented by the general formula (2), and B represents an amine compound represented by the following general formula (3)].

CXCR4 is the most common chemokine receptor expressed on the surface of many cancer cell types. In comparison to normal cells, cancer cells overexpress CXCR4, which correlates with cancer cell metastasis, angiogenesis, and tumor growth. CXCR4 antagonists can potentially diminish the viability of cancer cells by interfering with CXCL12-mediated pro-survival signaling and by inhibiting chemotaxis. Herein, we describe a series of CXCR4 antagonists that are derived from (S)-5,6,7,8-tetrahydroquinolin-8-amine that has prevailed in the literature. This series removes the rigidity and chirality of the tetrahydroquinoline providing 2-(aminomethyl)pyridine analogs, which are more readily accessible and exhibit improved liver microsomal stability. The medicinal chemistry strategy and biological properties are described.

The disclosure relates to chemokine CXCR4 receptor modulators and uses related thereto. The receptor modulators can be formulated to form pharmaceutical compositions comprising the disclosed compounds or pharmaceutically acceptable salts or prodrugs thereof. The compositions may be used for managing CXCR4 related conditions, typically prevention or treatment of viral infections abnormal cellular proliferation, retinal degeneration, inflammatory diseases, or as an immunostimulant or immunosuppressant or for managing cancer and may be administered with another active ingredient such as an antiviral agent or chemotherapeutic agent.

Page/Page column 0148; 0149, (2015/02/19)
[Object] The object of this invention is to provide a method for producing an optically active secondary alcohol at a high optical purity by hydrogenating a substrate carbonyl compound at a high efficiency using as a catalyst a ruthenium complex bearing as a ligand certain optically active diphosphine compound and a readily synthesized amine compound. [Solution] The method of producing an optically active secondary alcohol according to the present invention is characterized in that a substrate carbonyl compound (provided that 3-quinuclidinone, 3-quinuclidinone derivative having a substituent, and a ketone having an aromatic hydrocarbon group and a heterocycle are excluded) is reacted with hydrogen and/or a hydrogen donating compound in the presence of a ruthenium complex selected from the compounds expressed by following general formula (1) RuXYAB (1) [in the general formula (1), X and Y are the same or different from each other and denote a hydrogen atom or an anionic group, A denotes an optically active diphosphine expressed by the general formula (2), B denotes an amine compound expressed by following general formula (3)].
