Abstract
Extensive investigation on the molecular and electronic structure of 2-amino-5-trifluoromethyl-1,3,4-thiadiazole in the ground state and in the first excited state has been performed. The energy barrier corresponding to the conversion between imino and amino tautomers has been calculated, which indicates the existence of amino tautomer in solid state for the title compound. The FT-Raman and FT-IR spectra were recorded and compared with theoretical vibrational wavenumbers, and a good coherence has been observed. The MESP map, dipole moment, polarizability, and hyperpolarizability have been calculated to comprehend the properties of the title molecule. High polarizability value estimation of the title compound may enhance its bioactivity. Natural bonding orbital analysis has been done on monomer and dimer to investigate the charge delocalization and strength of hydrogen bonding, respectively. Strong hydrogen bonding interaction energies of 17.09/17.49 kcal mol-1 have been calculated at the B3LYP/M06-2X functional. The UV-vis spectrum was recorded and related to the theoretical spectrum. The title compound was biologically examined for anticancer activity by studying the cytotoxic performance against two human cancer cell lines (A549 and HeLa) along with the molecular docking simulation. Both molecular docking and cytotoxic performance against cancer cell lines show positive outcomes, and the title compound appears to be a promising anticancer agent.

Abstract
Condensation of 3,4-diaryl-2-imino-4-thiazoli-nes 1a-j with methanesulfonyl chloride gave methanesulfonamide derivatives 2a-j. Condensation of 2-cyanopyrazine, 4-cyanopyridine, and 2-cyanopyridine with 3,4-diaryl-2- imino-4-thiazolines 1h-m in the presence of sodium methoxide afforded amidine derivatives 3a-j. Compounds 2a-j and 3a-j were screened against various human cancer cell lines (COLO-205, HEP-2, A-549, IMR-32) and their percentage growth inhibition profile determined at 1 x 10(-5)M. The anti-inflammatory activity of these compounds was assessed using the carrageenan-induced paw edema model. Compound 2i exhibited 34.7% anti-inflammatory activity at 50 mg/kg p.o., which is comparable to standard care drug phenyl butazone (37% activity at 50 mg/kg p.o.).

Abstract
Anticancer activity studies of 2-(4-fluorophenylamino)-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazole (FABT), as one of the most promising derivatives from the N-substituted 2-amino-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazole set, have been continued. The tested compound inhibited proliferation of tumor cells derived from cancers of nervous system (medulloblastoma/rhabdosarcoma, neuroblastoma, and glioma) and peripheral cancers including colon adenocarcinoma and lung carcinoma. The anticancer effect of FABT was attributed to decreased cell division and inhibited cell migration. Furthermore, in anticancer concentrations it exerted a trophic effect in neuronal cell culture and had no influence on viability of normal cells including astrocytes, hepatocytes, and skin fibroblasts. Moreover, a prominent neuroprotective activity of FABT was observed in the neuronal cultures exposed to neurotoxic agents like serum deprivation and glutamate. To determine probability of tautomeric transition and indicate potential sites of interactions of FABT molecule with the receptor, quantum-chemical calculations with the ab initio Hartree-Fock model were made.

Abstract
We have synthesized a series of sulfonylureas and have tested their antimalarial activities, including inhibition of in vitro development of a chloroquine-resistant strain of Plasmodium falciparum, in vitro hemoglobin hydrolysis, hemozoin formation, and development of Plasmodium berghei in murine malaria. The most active antimalarial compound was (E)-1-[4'-(3-(2,4-difluorophenyl)acryloyl)phenyl]-3-tosylurea (22) with an IC(50) of 1.2microM against cultured P. falciparum parasites. Biological results suggest a fairly potent antimalarial activity for this derivative, but also imply that its activity may arise from an unknown mechanism. Indeed, these compounds may act against malaria parasites through multiple mechanisms.

Abstract
A number of N-substituted 2-amino-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazoles were synthesized and evaluated for their antiproliferative activities. The panel substitution included alkyl, aryl, and morpholinoalkyl derivatives. The structures of compounds were identified from elemental, IR, (1)H NMR, (13)C NMR and MS spectra analyses. The cytotoxicity in vitro against the four human cell lines: SW707 (rectal), HCV29T (bladder), A549 (lung), and T47D (breast) was determined. Alkyl and morpholinoalkyl derivatives exhibited significantly lower effect than phenyl ones. The highest antiproliferative activity was found for 2-(2,4-dichlorophenylamino)-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazole, with ID(50) two times lower (SW707, T47D) than for cisplatin studied comparatively as the control compound.

Abstract
The synthesis of a series of 3-(4-chlorophenyl)-[1,2-c]pyrazol(in)es substituted with benzenesulfonamide, N1,N3-disubstituted sulfonylurea, sulfonylthiourea pharmacophores, and some derived thiazolidinone and thiazoline ring systems is described. All the newly synthesized target compounds were subjected to the NCI-in vitro disease-oriented antitumor screening to be evaluated for their antitumor activity. Eight compounds namely; 2-4, 7, 8, 10, 13, and 16; showed promising broad spectrum antitumor activity against most of the tested subpanel tumor cell lines (GI50 < 100 microM). Compound 3, 4-(3-(4-chlorophenyl)-4H-indeno[1,2-c]pyrazol- 2-yl)-benzenesulfonamide; although it did not show the highest growth inhibitory value (GI50 (MG-MID) 13.2 microM), it proved to be the most active analog in this study with the highest cytostatic and cytotoxic potentials (TGI and LC50 (MG-MID) concentrations of 33.1 and 66.1 microM, respectively). In general, the oxidized pyrazoles displayed better antitumor activity than their parent pyrazoline analogs, whereas the benzenesulfonamides and the N1, N3-disubstituted sulfonylureas showed significant better antitumor spectrum than the sulfonylthioureido and the derived thiazole analogs.

Abstract
A series of new 5-substituted 2-(2,4-dihydroxyphenyl)-1,3,4-thiadiazoles has been synthesised and evaluated for their antiproliferative activity. The compounds were prepared by the reaction of the sulphinylbis(2,4-dihydroxythiobenzoyl) (STB) wit hydrazides or carbazates. The panel substitution included alkyl, alkoxy, aryl and heteroaryl derivatives. The structures of compounds were identified from the elemental, IR, (1)H NMR and MS spectra analysis. The highest antiproliferative activity against the cells of human cancer lines for 2-(2,4-dihydroxyphenyl)-5-(4-methoxybenzyloxy)-1,3,4-thiadiazole was found with ID(50) values comparable (HCV29T and SW707) or significantly lower (T47D) than for cisplatin applied as the reference compound. The influence of 5-substiution type of 2-(2,4-dihydroxyphenyl)-1,3,4-thiadiazoles on antiproliferative activity is discussed.

Abstract
A series of selected benzo[b]thiophene-5- and 6-sulfonamide derivatives previously reported to show cytotoxic activity and some others newly synthesized has been tested for the interactions with several CA isozymes, some of which are known to be involved in tumorigenesis (hCA IX), whereas others are ubiquitously found in many normal tissues (the cytosolic isoforms hCA I and II). The unsubstituted sulfonamides inhibited hCA I with inhibition constants in the range of 63-138 nM, hCA II with inhibition constants in the range of 6.3-8.8 nM, and hCA IX with inhibition constants in the range of 2.8-15 nM, being thus more active than clinically used inhibitors such as acetazolamide, methazolamide, ethoxzolamide, dichlorophenamide or indisulam (E 7070). Some of these derivatives also showed some selectivity for the inhibition of the tumor-associated (hCA IX) over the cytosolic isozyme hCA II. Although these derivatives may act on many targets other than the CAs (such as the NADH oxidase) or may induce apoptosis by accumulation of reactive oxygen species, it is quite important to try to decipher as many as possible of the potential mechanisms that lead to derivatives with potent antitumor activity in order to develop novel therapeutic strategies for the management of cancer.

Abstract
Synthesis of orthogonally protected (2S)-2-amino-3-(3-amino-4-hydroxy-phenyl)-propionic acid (10) suitable for solid phase peptide synthesis and its first use for the preparation of nonphosphorylated Grb2-SH2 domain antagonists (4a-c) are reported. The 3-aminotyrosine containing sulfoxide-cyclized hexapeptide (4b) exhibited potent Grb2-SH2 domain binding affinity with IC50 = 50 nM, which represents the highest affinity yet reported for a peptide inhibitor against Grb2-SH2 domain with only 6 residues free of phosphotyrosine or phosphotyrosine mimics. This potent small peptidomimetic 4b may be representative of a new class of therapeutically relevant Grb2-SH2 domain-directed agents, and acts as a chemotherapeutic lead for the treatment of erbB2-related cancers.

Abstract
PURPOSE The aim of the present study was to evaluate whether the transepithelial transport of the anticancer compound 4-toluenesulfonylureido-carnosine (Ts-carnosine) and the dipeptide moiety L-carnosine was due to a hPepT1 carrier-mediated flux. METHODS Transport experiments were conducted using Caco-2 cell monolayers and either reversed-phase HPLC-UV or liquid scintillation counting methods for quantification. pKa, LogD, and LogP were determined using the Sirius GlpKa meter. RESULTS L-carnosine was transported across the apical membrane with a Km,app of 2.48 +/- 1.16 mM and a Vmax of 2.08 +/- 0.34 nmol x cm(-2) x min(-1) and across the basolateral membrane with a Km,app of 7.21 +/- 3.17 mM and a Vmax of 0.54 +/- 0.10 nmol x cm(-2) x min(-1), and transepithelially with a Papp of 4.46 x 10(-2) +/- 6.4 x 10(-6) cm x min(-10). Ts-carnosine had an affinity (Ki) for hPepT1 of 2.33 +/- 0.54 mM; however, the transepithelial transport was low as compared to that of L-carnosine. CONCLUSIONS L-carnosine was transported across both the apical and basolateral membrane of Caco-2 cell monolayers in a carrier-mediated manner however, the transepithelial transport followed apparent simple non-saturable kinetics. Ts-carnosine had an affinity for hPepT1 but a relatively low transepithelial transport. This indicates that the transepithelial transport of L-carnosine and Ts-carnosine is not hPepT1 carrier-mediated and that L-carnosine is not a suitable dipeptide moiety for hPepT1-mediated absorption of sulfonamide-type anticancer compounds.

Abstract
A series of 9-sulfonylated/sulfenylated-6-mercaptopurines has been prepared by reaction of 6-mercaptopurine with sulfonyl/sulfenyl halides. These compounds constitute a new class of potent antimycobacterial agents, possessing MIC values against Mycobacterium tuberculosis H37Rv in the range of 0.39-3.39 microg/mL, as well as appreciable activity against Mycobacterium avium. Furthermore, a compound of this small series exhibited good activity (MIC under 1 microg/mL) against several drug resistant strains of M. tuberculosis.
