The title compound, ethyl 2-(4-methoxyphenyl)-1H-benzo[d]imidazole-5-carboxylate dihydrate (5), was synthesized and its crystal structure was studied by single-crystal X-ray diffraction technique. Compound 5 is crystallized in the centrosymmetric triclinic space group P1 ˉ with Z = 4 and Z′ = 2, and unit-cell parameters of a = 8.9190 (3) ?, b = 12.6888 (4) ?, c = 14.7111 (5) ?, α = 98.4855 (10)°, β = 101.6379 (9)°, γ = 95.4346 (10)° and V = 1599.43 (9) ?3. Its starting material, 4-fluoro-3-nitrobenzoic acid (1), is crystallized in the non-centrosymmetric monoclinic space group P21 and Z = 4 with unit-cell parameters of a = 3.7170 (4) ?, b = 12.6475 (13) ?, c = 15.5237 (15) ?, α = 90°, β = 91.9786 (16)°, γ = 90° and V = 729.35 (13) ?3. It was noted that strong hydrogen bonds play important roles in the crystal packing of both compounds, especially in 5, in which the co-crystallized water molecules act as both strong hydrogen bond donor and strong hydrogen bond acceptor. Graphical Abstract: Two molecule of compound 5 crystallized in a non symmetrical manner with four co-crystallized water molecules which play an important role in the crystal packing as strong hydrogen-bond donors.

A new palladium-catalyzed, heteroatom-directed strategy for C-H nitration of anilines is described. This C-H functionalization reaction is highly ortho-selective and results in very good yields. The highlight of the work is the use of pyrimidine as the removable directing group. This approach constitutes one of the rare methods of ortho-nitration of anilines, a reaction that is normally very difficult to achieve via traditional approaches.

Abstract A total of 51 novel benzimidazoles were synthesized by a 4-step reaction starting from basic compound 4-fluoro-3-nitrobenzoic acid under relatively mild reaction conditions. The structure of the novel benzimidazoles was confirmed by mass spectra as well as 1H NMR spectroscopic data. Out of the 51 novel synthesized compounds, 42 of them were screened for their antimycobacterial activity against Mycobacterium tuberculosis H37Rv strain using BacTiter-Glo Microbial Cell Viability (BTG) method. Results of activity screened using Alamar Blue method was also provided for comparison purposes. Two of the novel benzimidazoles synthesized showed moderately good activity with IC50 of less than 15 μM. Compound 5g, ethyl 2-(4-(trifluoromethyl)phenyl)-1-(2-morpholinoethyl)-1H-benzo[d]imidazole-5-carboxylate, was found to be the most active with IC50 of 11.52 μM.
Discovery of a potent and highly fluorescent sirtuin inhibitor

, p. 1857 - 1863 (2015/10/20)
In search for potent sirtuin inhibitors, a series of diversified 1,2-disubstituted benzimidazole analogues were synthesized using a one-pot method. The most potent compound in the series (BZD9L1) was discovered to show high autofluorescence which can be utilized to predict its localization in cells. More importantly, BZD9L1 displayed strong antiproliferative effects against a panel of cancer cells tested. Molecular docking studies also help to explain the observed structure-activity relationship.

Abstract The coagulation factor Xa (FXa) plays a central role in the blood coagulation cascade. Recent studies have shown that FXa is a particularly attractive target for the development of oral antithrombotic agents. In view of the excellent pharmaceutical properties of 1,2-phenylenediamine-based FXa inhibitors and the reported structureeactivity relationship (SAR) analysis of FXa inhibitors, we designed and synthesized a series of 3,4-diaminobenzoyl-based FXa inhibitors. Intensive SAR studies on this new series led to the discovery of 3,4-dimethoxyl substituted compound 7b. 7b is a highly potent, selective, direct FXa inhibitor with excellent in vivo antithrombotic activity.
