To find a novel acyl-CoA: cholesterol acyltransferase inhibitor, a series of sulfamide derivatives were synthesized and evaluated. Compound 1d, in which carboxymethyl moiety at the 5-position of Pactimibe was replaced by a sulfamoylamino group, showed 150-fold more potent anti-foam cell formation activity (IC50: 0.02 μM), 1.6-fold higher log D7.0 (4.63), and a slightly lower protein binding ratio (93.2%) than Pactimibe. Compound 1i, in which the octyl chain at the 1-position in 1d was replaced by an ethoxyethyl, showed markedly low log D7.0 (1.73) and maintained 3-fold higher anti-foam cell formation activity (IC50: 1.0 μM), than Pactimibe. The plasma protein binding ratio (PBR) of 1i was much lower than that of Pactimibe (62.5% vs. 98.1%), and its partition ratio to the rabbit atherosclerotic aorta after oral administration was higher than that of Pactimibe. Compound 1i at 10 μM markedly inhibited cholesterol esterification in atherosclerotic rabbit aortas even when incubated with serum, while Pactimibe had little effect probably due to its high PBR. In conclusion, compound 1i is expected to more efficiently inhibit the progression of atherosclerosis than Pactimibe.

The sulfamide functional group is increasingly relevant in both medicinal and bioorganic chemistry. We report here practical access to a series of N2,N5-substituted five-membered cyclosulfamides. The five-membered heterocyclic motif was prepared starting from proteogenic amino acids and chlorosulfonyl isocyanate via the Mitsunobu reaction. Selected chemical and spectral proprieties and the antimicrobial evaluation of these compounds are detailed.

A one-step synthesis of 5-oxazolecarbamates 1-11 can be easily carried out starting from N-acetylated and benzoylated aminoacids such as Gly, Ala, Leu, Phe, and chlorosulfonyl carbamates, prepared in situ by addition of alcohols on chlorosulfonyl isocyanate (CSI). The structure of the compounds was confirmed by X-Ray crystallography. A subsequent exocyclic N-alkylation gave substituted 12. 18 derivatives. Carbamate cleavage gave by spontaneous reopening substituted N-acylaminoamides, in excellent yields.

A series of new α-sulfamidophosphonate/sulfonamidophosphonate (4a–n) and cyclosulfamidophosphonate (5a–d) derivatives containing the quinoline or quinolone moiety was designed and synthesized via Kabachnik–Fields reaction in the presence of ionic liquid under ultrasound irradiation. This efficient methodology provides new 1,2,5-thiadiazolidine-1,1-dioxide derivatives 5a–d in one step and optimal conditions. The molecular structures of the novel compounds 4a–n and 5a–d were confirmed using various spectroscopic methods. All these compounds were evaluated for their in vitro antibacterial activity against Gram-negative (Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853) and Gram-positive (Staphylococcus aureus ATCC 27923) bacteria, in addition to three clinical strains (E. coli 1, P. aeruginosa 1, and S. aureus 1). Most of the tested compounds showed more potent inhibitory activities against both Gram-positive and -negative bacteria compared with the sulfamethoxazole reference. The following compounds, 4n, 4f, 4g, 4m, 4l, 4d, and 4e, are the most active sulfamidophosphonate derivatives. Furthermore, these molecules gave interesting zones of inhibition varying between 28 and 49 mm, against all tested bacterial strains, with a low minimum inhibitory concentration (MIC) value ranging from 0.125 to 8 μg/ml. All the synthesized derivatives were also evaluated for their in vitro antifungal activity against Fusarium oxyporum f. sp. lycopersici and Alternaria sp. The results revealed that all the synthesized compounds exhibited excellent antifungal inhibition and the compounds 4f, 4g, 4m, and 4i were the most potent derivatives with MIC values ranging from 0.25 to 1 μg/ml against the two tested fungal strains. The strongest inhibition of bacteria and fungi strains was detected by the effect of quinolone and sulfamide moieties.

Diarylpyrimidine derivatives (DAPYs) exhibit robust anti-HIV-1 potency, although they have been compromised by E138K variant and severe side-effects and been suffering from poor water solubility. In the present work, hydrophilic morpholine or methylsulfon
