Development of a Scalable Synthesis of the Small Molecule TGF beta R1 Inhibitor BMS-986260

A scalable route to the small molecule TGF beta R1 inhibitor BMS-986260 (1) was developed. This alternative approach circumvented the purification of intermediates by column chromatography and provided access to multikilogram quantities of the key intermediate, 6. The safety aspects of the synthetic approach to the other fragment of the API (TosMIC 10) were critically evaluated, and a robust process for its large-scale synthesis was successfully demonstrated.

Equilibrium Structures of Pyrazine, s-Triazine, and s-Tetrazine

In recent years, accurate equilibrium (r(e)) structures have been determined for pyridine, pyridazine, and pyrimidine. Here, we report accurate r(e) structures for the structurally related molecules pyrazine, s-triazine, and s-tetrazine, which were obtained using a composite approach based on explicitly correlated coupled-cluster theory (CCSD(T)-F12b) in conjunction with a large correlation-consistent basis set (cc-pCVQZ-F12) to take core-valence electron correlation into account. Additional terms were included to correct for the effects of iterative triple excitations (CCSDT), noniterative quadruple excitations (CCSDT-(Q)), and scalar relativistic contributions (DKH2-CCSD(T)). The performance of this computational procedure was established through test calculations on selected small molecules. For s-triazine, accurate experimental ground-state rotational constants (B-0) of the parent molecule and six D-3h isotopologues from the literature were used to determine a semiexperimental r(e) structure, which was found to be essentially identical with the best estimate from the current composite approach. The presently recommended equilibrium structural parameters of s-triazine are r(e)(CH) = 108.17 pm, r(e)(CN) = 133.19 pm, and theta(e)(NCN) = 125.95 degrees, with estimated uncertainties of +/- 0.10 pm and +/- 0.10 degrees, respectively. The predicted equilibrium geometries for pyrazine and s-tetrazine are expected to be of the same accuracy. We recommend for pyrazine: r(e)(CH) = 108.16 pm, r(e)(CN) = 133.34 pm, r(e)(CC) = 139.07 pm, theta(e)(CNC) = 115.60 degrees, and theta(e)(HCC) = 120.75 degrees; and for s-tetrazine: r(e)(CH) = 107.95 pm, r(e)(CN) = 133.39 pm, r(e)(NN) = 132.01 pm, and theta(e)(NCN) = 126.59 degrees.

Polysubstituted and ring-fused pyridazine systems from tetrafluoropyridazine

Tetrafluoropyridazine 1 reacts with a range of oxygen-, nitrogen-, sulfur- and carbon-centred nucleophiles to give, in general, products 2 arising from substitution of fluorine para to ring nitrogen. Subsequent reaction of the trifluoropyridazine derivatives 2 gave a range of 4,5-di-and tri-substituted products 3 and 6. Related reactions of tetrafluoropyridazine 1 with difunctional nucleophiles gave [6,6]-, [5,6]-and [6,5,61-polycyclic ring fused pyridazine scaffolds 4 and 9. Further functionalisation of scaffolds 4 by nucleophlic aromatic substitution processes involving displacement of fluorine atoms at activated sites ortho to ring nitrogen provide an indication of the synthetic possibilities offered using tetrafluoropyridazine as a starting material for the preparation of polysubstituted pyridazine and novel polyfunctional ring fused pyridazine systems with potential applications in the drug discovery arena.

Synthesis, heterocyclization and anti-tumour activity evaluation of some benzimidazole derivatives

Methylbenzimidazole 1 is converted to imidazole acrylic acid 3 via cyclo condensation with chloral followed by hydrolysis. Compound 3 also obtained from the reaction of o-phenylenediamine with maleic anhydride. Treatment of 1 with SeO2 yielded the oxidized product 4 (Aldehyde 4) which undergoes Wittig reaction using ester and Ph3P to furnish the acrylates 5. Compound 5 is also obtained by cyclocondensation of o-phenylenediamine and the corresponding maleate. Cyclization of 3 using Ac2O provides pyrroloimidazole 6. Imidazole 6 undergoes several transformations using HCI, ammonium hydroxide in neutral medium, o-phenylene diamine/HCI to provide acrylic acid 3, amide 7 and/or bicompound 8 respectively. Anilide 9 is obtained as a result of condensation of 3 with amines. Ester 5 undergoes 1,4-addition to benzimidazole ring to give the corresponding anilino derivative 10. Pyridazine cyclization is acheived by treatment of 5 with NH2OH in acidic medium. In vitro cytotoxicity is evaluated using SRB (sulphorhodamine-B) assay against two human cell lines, breast and liver carcinoma cell lines. The results show that compound 11 has strong activity against all cell lines tested.

Gas-phase UV absorption spectra of pyrazine, pyrimidine and pyridazine

The gas phase UV absorption spectra of pyrazine, pyrimidine and pyridazine were determined by using a D2-lamp coupled to a monochromator-PM system between 200 and 380 nm, at 353 +/- 3 K and at pressures lower than their vapor pressure (0.08-0.5 torr). The obtained spectra consist of a broad continuum with low intense absorption bands at 200-380 nm. Absorption of the investigated compounds at wavelengths > 290 nm is non-negligible (sigma(lambda) > 290 nm in the order of 10(-20) cm(2) molecule(-1)). These results indicate that, pyrazine, pyrimidine and pyridazine could be removed from the troposphere via photolysis reactions.

Optimization of Hexadentate Bispidine Ligands as Chelators for Cu-64(II) PET Imaging

The coordination chemistry of the hexadentate bispidine ligand L-1 with three pyridine, one pyridazine, and two tertiary amine donors with Cu-II and Zn-II is reported. The substitution of one of the two cis-disposed pyridine donors in-plane with the two tertiary amines of the bispidine backbone by a pyridazine group was predicted to substantially reduce distortion from planarity of the tetradentate subunit and therefore was assumed to lead to higher Cu-II complex stability. The X-ray single-crystal structures of the Zn-II and Cu-II complexes, which are in excellent agreement with the DFT- and MM-optimized structures, confirmed this prediction but indicated that deviation from planarity is appreciable. This also emerges from solution spectroscopy (UV/Vis/NIR and EPR of the Cu-II complex), which indicated that the in-plane ligand field is only slightly increased. The geometric parameters together with the lower basicity of pyridazine versus pyridine (pK(a) =2.33 vs. 5.23) are also in agreement with an only slightly more negative redox potential of the Cu-II/I couple (E degrees= 780 vs. 760 mV, MeCN, vs. Fc/Fc(+)), and the potentiometrically determined Cu-II stability constant with L-1 is slightly lower than that with the parent ligand L-2 (log K=12.7 vs. 14.5). Therefore, modification of the donor groups is a more promising approach to increasing the stabilities of these complexes and yields Cu-64(II) chelators that outperform known hexadentate bispidine ligands.
