- An efficient and convenient synthesis of acyl coa: Monoacylglycerol acyltransferase 2 inhibitor, 2-[2-(4-tert-butylphenyl)ethyl]-N-[4-(3-cyclopentylpropyl)-2-fluorophenyl]-1,2,3,4-tetrahydroisoquinoline-6-sulfonamide
-
An efficient and convenient synthesis of MGAT2 inhibitor, 2-[2-(4-tert-butylphenyl)ethyl]-N-[4-(3-cyclopentylpropyl)-2-fluorophenyl]-1,2,3, 4-tetrahydroisoquinoline-6-sulfonamide (1), is reported. The optimized route consists of an effective chlorosulfonylation and debromination, resulting in an increase in the total yield from 6.8% to 45%, compared with our previous method. This synthetic approach enabled the synthesis of 1 to be scaled-up to a multi-gram scale.

- Heterocyclic derivatives and their use as antithrombotic agents
-
The present invention relates to antithrombotic compounds comprising the group Q, Q having formula (I), wherein the substructure (i) is a structure selected from (a, b and c), wherein X is O or S; X′ being independently CH or N; and m is 0, 1, 2 or 3; wherein the group Q is bound through an oxygen atom or an optionally substituted nitrogen or carbon atom, or a pharmaceutically acceptable salt thereof or a prodrug thereof. The compounds of the invention are therapeutically active and in particular are antithrombotic agents.

- Inhibitors of phenylethanolamine N-methyltransferase and epinephrine biosynthesis. 2. 1,2,3,4-Tetrahydroisoquinoline-7-sulfonanilides.
-
1,2,3,4-Tetrahydroisoquinoline-7-sulfonanilides (1-14) related to 1,2,3,4-tetrahydroisoquinoline-7-sulfonamide (21,SK&F 29661) were prepared and studied for their ability to inhibit phenylethanolamine N-methyltransferase (PNMT) in vitro. The choice of substituents on the 7-phenyl group of the sulfonanilides was based on the Topliss approach to structure-activity relationship studies. Information about the importance of an acidic hydrogen atom on the sulfonamide nitrogen atom was obtained from the preparation and testing of a tertiary N-methylsulfonanilide (15). Other THIQ's (1,2,3,4-tetrahydroisoquinolines) containing sulfur substituents in the 7 position were prepared and tested and consisted of 7-N-benzyl and 7-N-phenethyl derivatives of SK&F 29661 (16-18) and 7-(phenacylthio)-and 7-(phenacylsulfonyl)-THIQ (19 and 20). The two most potent inhibitors were the 7-p-bromo- and -chlorosulfonanilides, 2 and 6. However, neither was an effective inhibitor of norepinephrine to epinephrine conversion when tested in an in vivo mouse assay at unit doses of 25 or 100 mg/kg.
