Abstract
Due to the rapidly growing bacterial resistance to antibiotics and the scarcity of novel agents under development, bacterial infections are still a pressing global problem, making new types of antibacterial agents, which are effective both alone and in combination with traditional antibiotics, urgently needed. In this paper, seven series of N-arylsulfonylindole analogs 5–11 bearing rhodanine moieties were synthesized, characterized, and evaluated for antibacterial activity. According to the in vitro antimicrobial results, half of the synthesized compounds showed potent inhibition against four Gram-positive bacteria, with MIC values in the range of 0.5–8 µg/mL. For multidrug-resistant strains, compounds 6a and 6c were the most potent, with MIC values of 0.5 µg/mL, having comparable activity to gatifloxacin, moxiflocaxin and norfloxacin and being 128-fold more potent than oxacillin (MIC = 64 µg/mL) and 64-fold more active than penicillin (MIC = 32 µg/mL) against Staphylococcus aureusATCC 43300.

Abstract
Pancreatic cancer is the leading cause of cancer death worldwide with a poor survival rate. The objective of this study was to determine the mechanism of action of a novel antimitotic and Stat3 inhibitor, LTP-1, on human pancreatic cancer in vitro and in vivo. We found that LTP-1 inhibited pancreatic cancer cell growth and viability with significant G2/M arrest and disruption of microtubule dynamics. LTP-1 also caused G2/M arrest-independent Stat3 dephosphorylation along with ERK activation, which indicated the possible dual function of LTP-1. Long-term treatment of LTP-1 also induced polyploidy, activated caspases, induced subG1 cell population, and therefore, triggered pancreatic cancer cell apoptosis. Finally, we used an in vivo xenograft model to demonstrate that LTP-1 suppressed the growth of pancreatic adenocarcinoma. In summary, our data suggest that LTP-1 may alter microtubule dynamics, which ultimately causes polyploidy and apoptosis, thereby inhibiting pancreatic cancer growth in vitro and in vivo. This study provides evidence that LTP-1 could be a potential therapeutic agent for further development of pancreatic cancer treatment.

Abstract
Carbonic anhydrase inhibitors AZA, EZA, and 4-acetamidobenzsulfonamide were found to inhibit human AQP4-M23 mediated water transport by 80%, 68%, and 23%, respectively, at 20 microM in an in vitro functional assay. AZA was found to have an IC50 against AQP4 of 0.9 microM. Phloretin was inactive under the same conditions.

Abstract
8-(Sulfostyryl)xanthine derivatives were synthesized as water-soluble A2A-selective adenosine receptor (AR) antagonists. meta- and para-sulfostyryl-DMPX (3,7-dimethyl-1-propargylxanthine) derivatives 11a and 11b exhibited high affinity to rat A2A-AR in submicromolar concentrations, and were 20- to 30-fold selective versus rat A1-AR. Styryl-DMPX derivatives were inactive at human A2B- and A3-AR. 1,3-Dipropyl-8-p-sulfostyrylxanthine (13) or only a 7-methyl derivative (14) showed similar (13) or higher (14) A2A affinity than 11a and 11b but showed no (13) or only a low degree (14) of selectivity versus A1-, A2B-, and A3-AR. The A2A-selective sulfostyryl-DMPX derivatives exhibit high water-solubility and may be useful research tools for in vivo studies.
