Discovery of novel tetrahydroisoquinoline derivatives as potent and selective factor Xa inhibitors

A series of novel 2,7-disubstituted tetrahydroisoquinoline derivatives were designed and synthesized. Among these derivatives, compounds 1 and 2 (JTV-803) exhibited potent inhibitory activity against FXa and good selectivity with respect to other serine proteases (thrombin, plasmin, and trypsin). In addition, compound 2 exhibited potent anti-FXa activity after intravenous and oral administration to cynomolgus monkey, and showed a dose-dependent antithrombotic effect in a rat model of venous thrombosis.

Design and Synthesis of Potent, Selective Inhibitors of Protein Arginine Methyltransferase 4 against Acute Myeloid Leukemia

PRMT4 is a type I protein arginine methyltransferase and plays important roles in various cellular processes. Overexpression of PRMT4 has been found to be involved in several types of cancers. Selective and in vivo effective PRMT4 inhibitors are needed for demonstrating PRMT4 as a promising therapeutic target. On the basis of compound 6, a weak dual PRMT4/6 inhibitor, we constructed a tetrahydroisoquinoline scaffold through a cut-and-sew scaffold hopping strategy. The subsequent SAR optimization efforts employed structure-based approach led to the identification of a novel PRMT4 inhibitor 49. Compound 49 exhibited prominently high potency and selectivity, moderate pharmacokinetic profiles, and good antitumor efficacy in acute myeloid leukemia xenograft model via oral administration, thus demonstrating this compound as a useful pharmacological tool for further target validation and drug development in cancer therapy.

A method for the manufacture of compounds containing an alpha- oxy phosphorus group is disclosed. A P-X component having at least one P-X bond, whereby the phosphorus of the P-X bond has the +3 oxidation state with X being C1 or Br, is reacted in a specific equivalent ratio with a compound containing an alpha-oxy carboxylic acid group, followed by conducting the reaction and optionally adding a quenching agent at the end of the reaction. The compounds containing an alpha-oxy phosphorus group formed are then recovered.

The Photocatalyzed Aza-Henry Reaction of N-Aryltetrahydroisoquinolines: Comprehensive Mechanism, H?- versus H+-Abstraction, and Background Reactions

The cross-dehydrogenative coupling (CDC) reaction of N-aryltetrahydroisoquinolines (THIQ) is one of the most exploited photocatalytic transformation and a test reaction for an exceptional variety of catalysts. However, its mechanism remained unclear concerning involved intermediates, reactive pathways of the amine radical cation and the influence of oxygen and the light source. Therefore, nuclear magnetic resonance (NMR), electron spin resonance (ESR) and synthetic methods were combined to provide a comprehensive picture of the reaction mechanism using Ru(bpy)3Cl2 as a photocatalyst under aerobic and anaerobic conditions. The reaction profiles and involved intermediates were monitored and analyzed by NMR spectroscopy. Several intermediates contributing to product formation were identified, the iminium ion, the hydroperoxide and dimer of THIQ, and a new ring opened intermediate, cleaved at the benzylic C-N bond. Mechanistic evidence is given that under anaerobic conditions preferentially the alpha-amino radical is formed by deprotonation, in contrast to the formation of iminium ions via H?-abstraction in the presence of oxygen. Further, the light-induced background reaction in the absence of the catalyst was studied in detail, revealing that the product formation rate is correlated to the intensity and wavelength of the light source and that oxygen is essential for an efficient conversion. The reaction rate and efficiency is comparable to previously reported photocatalytic systems, performed under aerobic conditions in combination with intense blue light sources. Thus, the multitude of reaction parameters investigated reveals the preference for hydrogen atom or proton abstraction in photoreactions and allows to assess the influence of experimental conditions on the mechanistic pathways.

Synthesis of thiophene and N-substituted thieno[3,2-d] pyrimidine derivatives as potent antitumor and antibacterial agents

A novel series of carbamothioylamino-benzene-sulfonamide-thiophene-carboxylates 4a-c and thieno[3,2-d]pyrimidin-2-yl-amino-benzene-sulfonamides 5a-c were synthesized in a series of synthetic steps and were used as key intermediates for the synthesis of thienotriazolopyrimidine-benzene-sulfonamide derivatives 6a-c and 7a-c. Thieno[3,2-d]pyrimidinones (8 and 9) were also prepared. Compound 9 was used as an intermediate for the synthesis of imidazole/1,2,4-triazole and tetrazine functionalized thieno[3,2-d]pyrimidine derivatives (10-12). Pyrrole derivatives/pyrrolopyrimidine/pyrrolotriazolopyrimidine functionalized thiophenes (15-19) were also synthesized. Structures of the newly synthesized compounds were established by elemental analysis and spectral data. Most of the newly synthesized compounds were evaluated for their in vitro activity against three human tumor cell lines, namely, liver cancer (HepG-2), colon cancer (HT-29) and lung cancer (NCI-H460), using doxorubicin as standard. Compounds 16 (GI50 = 0.02, 0.04 and 0.06 mumol L-1, resp.) and 19b (GI50 = 0.02, 0.03 and 0.05 mumol L-1, resp.) showed higher activity against all cell lines than doxorubicin. Most of the compounds were also screened for antibacterial activity using ciprofloxacin as standard drug. Compounds 4b and 6b, both containing benzenesulfonamide linked to N-, 10 bearing imidazole moiety, and 15 and 19b,c with a thiophene-2-carboxylic acid chain, exhibited high activity against Gram-positive and Gram-negative bacteria.

Dynamic combinatorial chemistry with hydrazones: Libraries incorporating heterocyclic and steroidal motifs

We expand the possibilities in hydrazone based dynamic combinatorial chemistry with a series of new building blocks incorporating heterocyclic motifs. The synthetic procedure allows efficient access to building blocks with the general structure (MeO)2CH-Heterocycle-C(O)NHNH2, originating from heterocycles with an amine and an ester functionality. The equilibrium distribution of macrocyclic N-acyl hydrazones formed upon deprotection of the building blocks with TFA in organic solvents is reported. The mixing behaviour of these heterocycle-based building blocks with our cholate-based building blocks is described, particularly the observation of kinetic intermediates that disappear following ‘proof-reading’.
