A series of benz-fused five-membered heterocyclic compounds were designed and synthesized as novel tubulin inhibitors targeting the colchicine binding site. Among them, compound 4d displayed the highest antiproliferative activity against four cancer cell lines with an IC50 value of 4.9?μM in B16-F10 cells. Compound 4d effectively inhibited tubulin polymerization in vitro (IC50 of 13.1?μM). Further, 4d induced cell cycle arrest in G2/M phase. Finally, 4d inhibited the migration of cancer cells in a dose-dependent manner. In summary, these results suggest that compound 4d represents a new class of tubulin inhibitors deserving further investigation.

Visible-Light-Photocatalyzed Reductions of N-Heterocyclic Nitroaryls to Anilines Utilizing Ascorbic Acid Reductant
Todorov, Aleksandar R.,Aikonen, Santeri,Muuronen, Mikko,Helaja, Juho
supporting information, p. 3764 - 3768 (2019/05/24)
A photoreductive protocol utilizing [Ru(bpy)3]2+ photocatalyst, blue light LEDs, and ascorbic acid (AscH2) has been developed to reduce nitro N-heteroaryls to the corresponding anilines. Based on experimental and computational results and previous studies, we propose that the reaction proceeds via proton-coupled electron transfer between AscH2, photocatalyst, and the nitro N-heteroaryl. The method offers a green catalytic procedure to reduce, e.g., 4-/8-nitroquinolines to the corresponding aminoquinolines, substructures present in important antimalarial drugs.

A previous publication from this lab (Patrick, et al. Bioorg. Med. Chem. 2016, 24, 2451-2465) explored the antitrypanosomal activities of novel derivatives of 2-(2-benzamido)ethyl-4-phenylthiazole (1), which had been identified as a hit against Trypanosoma brucei, the causative agent of human African trypanosomiasis. While a number of these compounds, particularly the urea analogues, were quite potent, these molecules as a whole exhibited poor metabolic stability. The present work describes the synthesis of 65 new analogues arising from medicinal chemistry optimization at different sites on the molecule. The most promising compounds were the urea derivatives of 2-aryl-benzothiazol-5-amines. One such analogue, (S)-2-(3,4-difluorophenyl)-5-(3-fluoro-N-pyrrolidylamido)benzothiazole (57) was chosen for in vivo efficacy studies based upon in vitro activity, metabolic stability, and brain penetration. This compound attained 5/5 cures in murine models of both early and late stage human African trypanosomiasis, representing a new lead for the development of drugs to combat this neglected disease.

Iron and palladium(II) phthalocyanines as recyclable catalysts for reduction of nitroarenes
Verma, Praveen Kumar,Bala, Manju,Thakur, Kavita,Sharma, Upendra,Kumar, Neeraj,Singh, Bikram
, p. 1258 - 1267 (2014/07/21)
Iron(II) and palladium(II) phthalocyanines have been established as recyclable heterogeneous catalysts for the reduction of aromatic nitro compounds to corresponding amines using diphenylsilane/sodium borohydride as hydrogen sources in ethanol. Various reducible functional groups, such as acetyl, ester, cyano, amide, sulphonamide and carboxylic acid etc. were well tolerated, and the methods were applicable up to gram scale. Mechanistic studies showed that reduction of nitro group proceed through direct (nitroso) pathway and possibly iron or palladium phthalocyanines activates nitro group for reduction. FePc and PdPc also catalyzed the generation of hydrogen from the combination of diphenylsilane/sodium borohydride and ethanol.

Structure-activity relationships of N-phenyl-N′-benzothiazol-6-ylurea synthetic derivatives: Cytokinin-like activity and adventitious rooting enhancement
Rolli, Enrico,Incerti, Matteo,Brunoni, Federica,Vicini, Paola,Ricci, Ada
experimental part, p. 159 - 165 (2012/03/27)
Some years ago we demonstrated the cytokinin-like activity of the synthetic N-phenyl-N′-benzothiazol-6-ylurea (PBU) and a relevant adventitious rooting adjuvant activity of symmetric urea derivatives devoid of any cytokinin- or auxin-like activity per se. Here we report the synthesis and the biological activity evaluation of nine symmetric or asymmetric ureas/thioureas, structurally related to PBU. None of them show cytokinin-like activity, while we demonstrate for the first time that PBU interacts with Arabidopsis cytokinin receptor CRE1/AHK4 in a heterologous bioassay system. Among the PBU derivatives, all the symmetric ureas/thioureas show an adventitious rooting adjuvant activity in various bioassays, confirming that this activity is strictly dependent on their chemical structure.
