Gold(I)-catalyzed intramolecular tandem addition/Friedel – Crafts reactions between acyclic enamides and 1-arylalkynes

Electron-deficient acyclic enamine derivatives react with electron-rich 1-arylalkynes using cationic gold(I) species as catalysts in an intramolecular process to form annulated 1-amido-substituted indene derivatives as the major products. Yields for this process range between 21% and 98%. In some cases, a two-step process that includes a subsequent alkene isomerization is needed.

Processes for the production of heterocyclic compounds

A ketonic heterocyclic compound having at least two heteroatoms in the ring is prepared by reacting a difunctional compound having the general formula STR1 in which R1, R2, R3 and R4 are members of the group consisting of aliphatic, aromatic, cycloaliphatic and heterocyclic hydrocarbons which may contain functional groups selected from –OH, –OR5, –COOH, –COOR5, –CN, –Cl, –Br, –I, –F, and –CO–R5, wherein R5 is an aliphatic, aromatic, cycloaliphatic or heterocyclic hydrocarbon; X is oxygen or sulphur; Y is sulphur or nitrogen; n is an integer ranging from 1 to 3, or zero; R6 is a hydrogen or a hydrocarbon radical included in the above definition of R1 R2 R3 and R4 ; and m is the valence of Y, with carbon monoxide and oxygen in the presence of a catalyst selected from selenium, selenium compounds and complexes of copper, in the temperature range of from room temperature to 80 C and in the pressure range of from 1 to 10 atmospheres.

Design, synthesis and antitumor study of a series of N-Cyclic sulfamoylaminoethyl substituted 1,2,5-oxadiazol-3-amines as new indoleamine 2, 3-dioxygenase 1 (IDO1) inhibitors

Indoleamine 2, 3-dioxygenase 1 (IDO1) plays a key role in tryptophan catabolism which is an important mechanism in immune tolerance. The small molecule epacadostat is the most advanced IDO1 inhibitor, but its phase III trials as a single agent or in combinations with PD-1 antibody failed to show appreciable objective responses. To gain more insight on the antitumor efficacy of IDO1 inhibitors, we have designed a series of analogues of epacadostat by incorporating a cyclic aminosulfonamide moiety as the sidechain capping functionality. Compound 5a was found to display significant potency against recombinant hIDO1 and hIDO1 expressed HEK293 cancer cells. This compound has improved physico-chemical properties, acceptable PK parameters as well as optimal cardiac safety. Similar to epacadostat, 5a is ineffective as single agent in the CT-26 syngeneic xenograft model, however, the combination of 5a with PD-1 antibody showed both elevated tumor growth inhibition and prolonged median life span.

Hepatitis C replication inhibitors that target the viral NS4B protein

We describe the preclinical development and in vivo efficacy of a novel chemical series that inhibits hepatitis C virus replication via direct interaction with the viral nonstructural protein 4B (NS4B). Significant potency improvements were realized through isosteric modifications to our initial lead 1a. The temptation to improve antiviral activity while compromising physicochemical properties was tempered by the judicial use of ligand efficiency indices during lead optimization. In this manner, compound 1a was transformed into (+)-28a which possessed an improved antiviral profile with no increase in molecular weight and only a modest elevation in lipophilicity. Additionally, we employed a chimeric “humanized” mouse model of HCV infection to demonstrate for the first time that a small molecule with high in vitro affinity for NS4B can inhibit viral replication in vivo. This successful proof-of-concept study suggests that drugs targeting NS4B may represent a viable treatment option for curing HCV infection.

Copper-catalyzed coupling of amides and carbamates with vinyl halides

(Matrix presented) A general and efficient copper-catalyzed method for the amidation of vinyl bromides and iodides has been developed. This protocol uses a combination of 5 mol % copper iodide and 20 mol % N,N?-dimethyl ethylenediamine. Substrates bearing ester, silyl ether, and amino groups were successfully coupled under the reaction conditions. The double bond geometry of the vinyl halides was retained under the reaction conditions.
