The restoration of damaged articular cartilage is a long-pursued goal in regenerative medicine. Chondrocyte-specific differentiation of mesenchymalstemcells (MSCs) may be an effective means of repairing damaged cartilage. We identified small molecule 6 with sulfonamide as an agent that promotes specific chondrogenic differentiation of human adipose-derived MSCs (hASCs). Unlike other chondrogenic

What's the potential? An anodic oxidation/organocatalytic α‐arylation of aldehydes using substituted electron‐rich aromatic compounds has been developed. The method gives access to meta‐substituted anilines and dihydrobenzofurans in good yields and excellent enantioselectivity (see scheme; Pg=protecting group). This method is an example of a new concept combining organocatalysis with electrochemistry

study aimed to develop a new class of IDH1(R132H) inhibitors as potent antitumor agents. Method: A biochemical assay was developed to find inhibitors of IDH1(R132H) mutant enzyme. Chemical synthesis and structure-activityrelationship studies were used to find compounds with improved potency. Antitumor activities of selected compounds were evaluated. Results: A series of aromatic sulfonamide compounds

Use of a compound of Formula 1 for inducing differentiation of mesenchymal stem cells to chondrocytes, and a pharmaceutical composition for treating a cartilage disease, which includes chondrocytes in which differentiation from mesenchymal stem cells is induced by the compound of Formula 1, are provided. Differentiation of the mesenchymal stem cells treated with the compound of Formula 1 to chondrocytes is specifically induced, and thus the compound can be used to effectively treat a cartilage disease such as arthritis, cartilage damage, and a cartilage defect.

C−C cleavage to arylation. Enantioselective α-arylation of simple aliphatic ketones has been achieved via chiral primary amine catalyzed asymmetric retro-Claisen cleavage involving β-diketones and para-quinone monoimines that facilitates the construction of α-aryl tertiary carbon stereocenters in good yields and high enantioselectivities.
