In the face of emerging infectious diseases, there remains an unmet need for vaccine development where adjuvants that enhance immune responses to pathogenic antigens are highly desired. Using high-throughput screens with a cell-based nuclear factor κB (NF-κB) reporter assay, we identified a sulfamoyl benzamidothiazole bearing compound 1 that demonstrated a sustained activation of NF-κB after a primary stimulus with a Toll-like receptor (TLR)-4 agonist, lipopolysaccharide (LPS). Here, we explore systematic structure–activity relationship (SAR) studies on compound 1 that indicated the sites on the scaffold that tolerated modification and yielded more potent compounds compared to 1. The selected analogs enhanced release of immunostimulatory cytokines in the human monocytic cell line THP-1 cells and murine primary dendritic cells. In murine vaccination studies, select compounds were used as co-adjuvants in combination with the Food and Drug Administration approved TLR-4 agonistic adjuvant, monophosphoryl lipid A (MPLA) that showed significant enhancement in antigen-specific antibody titers compared to MPLA alone. Additionally, our SAR studies led to identification of a photoaffinity probe which will aid the target identification and mechanism of action studies in the future.

Ammonium chloride-catalyzed four-component sonochemical synthesis of novel hexahydroquinolines bearing a sulfonamide moiety

, p. 54 - 64 (2015/03/04)
Ammonium chloride as a very inexpensive and readily available reagent efficiently catalyzes one-pot four-component condensation of dimedone with aromatic aldehyde, malononitrile or ethyl cyanoacetate, and sulfonamide derivatives in ethanol at 70°C under ultrasonic irradiation to afford the corresponding 2-amino-4-aryl-1,4,5,6,7,8-hexahydroquinolines bearing a sulfonamide moiety in high yields. In comparison to conventional methods, high yields, easy work-up, and short reaction time are advantages of this sonochemical procedure. The effects of the catalyst, solvent, and temperature are assessed.

, p. 2416 - 2426 (2014/05/06)
A novel series of 1,2-benzisothiazol-3-one derivatives was synthesized and their biological activities were evaluated for inhibiting caspase-3 and -7 activities, in which some of them showed low nanomolar potency against caspase-3 in vitro and significant protection against apoptosis in a camptothecin-induced Jurkat T cells system. Among the tested compounds, compound 5i exhibited the most potent caspase-3 inhibitory activity (IC50 = 1.15 nM). The molecular docking predicted the interactions and binding modes of the synthesized inhibitor in the caspase-3 active site.

Measles virus (MV) is one of the most infectious pathogens known. In spite of the existence of a vaccine, approximately 350000 deaths/year result from MV or associated complications. Antimeasles compounds could conceivably diminish these statistics and pr
Synthesis and antimicrobial evaluation of guanylsulfonamides

A series of guanylsulfonamides, 2-amino-9-[2-substituted-4-(4-substituted piperidin-1-sulfonyl)phenyl]-1,9-dihydropurin-6-ones, was synthesized by adopting reductive aminoformylation of 2-amino-5-nitro-6-[4-(piperidin-1-sulfonyl)phenylamino]-3H-pyrimidin- 4-one and subsequent intramolecular ring condensation as key steps. All the guanylsulfonamides were assayed for their in vitro antibacterial activities against Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus aureus, and Streptococcus faecalis, and their antifungal activities against Aspergillus flavus, Aspergillus niger, and Candida albicans. Of the guanylsulfonamides, 13e and 13f displayed better antibacterial activities than that of Norfloxacin against the bacterial strains S. aureus and S. faecalis except 13f against S. faecalis, which exhibited the activity similar to that of Norfloxacin. Against the fungal strains A. flavus and A. niger, 13g and 13h showed similar activities to that of Griseoflavin-16 except 13h against A. niger, which displayed a profound drop in the activity compared to that of Griseoflavin-16. The remarkable inhibition of the growth of the bacterial and fungal strains makes these substances promising microbial agents.
