Convenient One-Pot Two-Step Synthesis of Symmetrical and Unsymmetrical Diacyl Ureas, Acyl Urea/Carbamate/Thiocarbamate Derivatives, and Related Compounds

A wide range of chemicals such as amides, hydrazides, amines, alcohols, carbazate, and sulfonate were reacted with acyl isocyanates generated by the reaction of primary amides with oxalyl chloride to give symmetrical and unsymmetrical diacyl urea derivatives, acyl ureas/carbamates/thiocarbamates, and related compounds. This method provides means for convenient one-pot, two-step synthesis of compounds bearing urea, carbamate, and other functional groups from cheap and commercially available starting reagents. It is expected that the results presented in this report will expand the medicinal chemist’s toolbox.

Synthesis, antitumor activity and mechanism of action of novel 1,3-thiazole derivatives containing hydrazide–hydrazone and carboxamide moiety

A series of novel 2,4,5-trisubstituted 1,3-thiazole derivatives containing hydrazide–hydrazine, and carboxamide moiety including 46 compounds T were synthesized, and evaluated for their antitumor activity in vitro against a panel of five human cancer cell lines. Eighteen title compounds T displayed higher inhibitory activity than that of 5-Fu against MCF-7, HepG2, BGC-823, Hela, and A549 cell lines. Especially, T1, T26 and T38 exhibit best cytotoxic activity with IC50values of 2.21?μg/mL, 1.67?μg/mL and 1.11?μg/mL, against MCF-7, BCG-823, and HepG2 cell lines, respectively. These results suggested that the combination of 1,3-thiazole, hydrazide–hydrazone, and carboxamide moiety was much favorable to cytotoxicity activity. Furthermore, the flow cytometry analysis revealed that compounds T1 and T38 could induce apoptosis in HepG2 cells, and it was confirmed T38 led the induction of cell apoptosis by S cell-cycle arrest.

Synthesis and antitumor activity of novel N-benzoyl-N'-substituted pyrimidinyl (thio)semicarbazide derivatives

A series of substituted pyrimidinyl (thio)semicarbazide derivatives were designed and synthesized. The antitumor results showed that the activity of thiosemicarbazide compounds (series II) was generally higher than that of the corresponding semicarbazide derivatives (series I). Among them, IIk displayed higher cytotoxicity against HL-60, BGC-823 and Bel-7402 than that of adriamycin and exhibited broad in vitro cytotoxicity against 13 human tumor cell lines. Meanwhile, the cytotoxic selectivity and anti-multidrug resistance were evaluated, and IIk exhibited selective cytotoxicity against cancer cells in comparison to human normal cells and had significant anti-multidrug resistance capability. The bioassay results showed that IIk showed great promise as a potent lead compound for further antitumor discovery.

Acylurea connected straight chain hydroxamates as novel histone deacetylase inhibitors: Synthesis, SAR, and in vivo antitumor activity

Thirty-six novel acylurea connected straight chain hydroxamates were designed and synthesized. Structure-activity relationships (SAR) were established for the length of linear chain linker and substitutions on the benzoylurea group. Compounds 5g, 5i, 5n, and 19 showed 10-20-fold enhanced HDAC1 potency compared to SAHA. In general, the cellular potency pIC50 (COLO205) correlates with enzymatic potency pIC50 (HDAC1). Compound 5b (SB207), a structurally simple and close analogue to SAHA, is more potent against HDAC1 and HDAC6 compared to the latter. As a representative example of this series, good in vitro enzymatic and cellular potency plus an excellent pharmacokinetic profile has translated into better efficacy than SAHA in both prostate cancer (PC3) and colon cancer (HCT116) xenograft models.

Synthesis and activity evaluation of benzoylurea derivatives as potential antiproliferative agents

3-Haloacylamino benzoylureas (3-HBUs) consist of a new family of tubulin ligands that kill cancer cells through mitotic arrest. In exploring the structure-activity relationship (SAR), 17 analogues defined through variations of formylurea at the 1-position

Synthesis and anthelmintic activity of 3'-benzoylurea derivatives of 6-phenyl-2,3,5,6-tetrahydroimidazo[2,1-b]thiazole

Reaction of 3-amino derivatives of the nematocides tetramisole and levamisole with variously substituted benzoylisocyanates gave a series of benzoylureas I which were tested for activity against helminths and ectoparasites. Compounds bearing 2,6-difluoro and 4-trifluoromethyl substituents had potent nematocidal activity in both mice and sheep. No antiectoparasitic activity was observed.

CONDENSATION OF ACYL CHLORIDE ON SODIUM CYANATE : PREPARATION OF ACYL ISOCYANATES

The catalytic effects of various metal halides and solvents on the reaction of benzoyl chloride with sodium cyanate were studied.It has been found that SnCl4, and ZnCl2 catalyze the reaction to give the corresponding acyl isocyanates in good yields.The scope of the reaction was studied and a number of aroyl isocyanates and their derivatives were prepared.A few non aromatic isocyanates and their derivatives were also prepared.

Reactions de cycloaddition entre acyl (ou thioacyl) isocyanates (ou isothiocyanates) et isocyanates (ou isothiocyanates)

cycloaddition of an acylisocyanate (1a-1f) to an isocyanate (2a-2c) affords 2,4-dioxo-3,4-dihydro-1,3,5-2H-oxadiazine (4a-4j). Kinetic addition is observed with chloroacetyl (1g) or phenoxyacetyl (1h) isocyanate and methyl isocyanate (2a) to yield a dioxoazetidine (3a and 3b respectively).The reaction of N-dimethylcarbamoyl isothiocyanate (1c) with aromatic isocyanate (2c) or isothiocyanates (2d and 2e) is a cycloaddition too, yielding thioxo (4k) and dithioxo-oxadiazines (4l and 4m).But with the aliphatic isocyanates (2a and 2b) we have observed a preliminary rearrangement of N-dimethylcarbamoyl isothiocyanate 1i to N-dimethylthiocarbamoyl isocyanate 1j and we have obtained 1,3,5-2H-thiadiazines (4n and 4p).
