Abstract
3,4-Disubstituted pyrrolidinesulfonamides were synthesized and screened for their antimicrobial activity. Title compounds were established as potent antibacterial and antifungal agents. Noteworthy antimicrobial activity was found for the title compounds against the tested microorganisms. They exhibit comparable results with standard drugs. Besides the in vitro antimicrobial activity, the synthesized compounds were evaluated for their in silico inhibitory activity on active site of β-glucosidase enzyme. In silico studies were done by GOLD docking method against β-glucosidase 3VKK (PDB Id). In silico studies were conducted to evaluate the ability of synthesized compounds to inhibit the β-glucosidase enzyme. The results revealed that 3,4-disubstitutedpyrrolidinesulfonamides are the potent β-glucosidase inhibitors by binding at the active site. A sensible inhibition against β-glucosidases was observed for the compound with 13,4-oxadizole ring has higher β-glucosidase inhibition activity than the other compounds. The free energy of binding and inhibition constant (Ki) of the docked compounds were evaluated and presented.

Abstract
Thieno[3,2-e]-1,2-thiazine-6-sulfonamide 1,1-dioxides, which have a quaternary ammonium moiety incorporated into their structures, were synthesized. All of the quaternary ammonium salts prepared in the present study are potent inhibitors of both human carbonic anhydrase-II and recombinant human carbonic anhydrase-IV; they are significantly more potent as inhibitors of these carbonic anhydrase isozymes than the previously reported inhibitor quaternary ammonium homosulfanilamide. By virtue of the permanent cationic charge on these compounds they are anticipated to be membrane-impermeable inhibitors of carbonic anhydrase. Spiro quaternary ammonium compounds, such as 15 and 16, when formed by intracellular cyclization following transport of a suitable precursor molecule, such as 14, may be selective prolonged inhibitors of cytosolic carbonic anhydrase due to intracellular entrapment.

Abstract
Carbonic anhydrases (CAs, EC 4.2.1.1) are wide-spread enzymes, present in mammals in at least 14 different isoforms. Some of these isozymes are cytosolic (CA I, CA II, CA III, CA VII, CA XIII), others are membrane-bound (CA IV, CA IX, CA XII and CA XIV), CA V is mitochondrial and CA VI is secreted in the saliva and milk. Three cytosolic acatalytic forms are also known (CARP VIII, CARP X and CARP XI). The catalytically active isoforms, which play important physiological and patho-physiological functions, are strongly inhibited by aromatic and heterocyclic sulfonamides. The catalytic and inhibition mechanisms of these enzymes are understood in great detail, and this greatly helped the design of potent inhibitors, some of which possess important clinical applications. The use of such CA inhibitors (CAIs) as antiglaucoma drugs are discussed in detail, together with the recent developments that led to isozyme-specific and organ-selective inhibitors. A recent discovery is connected with the involvement of CAs and their sulfonamide inhibitors in cancer: many potent CAIs were shown to inhibit the growth of several tumor cell lines in vitro and in vivo, thus constituting interesting leads for developing novel antitumor therapies. Future prospects for drug design of inhibitors of these ubiquitous enzymes are dealt with. Although activation of CAs has been a controversial issue for some time, recent kinetic, spectroscopic and X-ray crystallographic experiments offered an explanation of this phenomenon, based on the catalytic mechanism. It has been demonstrated recently, that molecules that act as carbonic anhydrase activators (CAAs) bind at the entrance of the enzyme active site participating in facilitated proton transfer processes between the active site and the reaction medium. In addition to CA II-activator adducts, X-ray crystallographic studies have been also reported for ternary complexes of this isozyme with activators and anion (azide) inhibitors. Structure-activity correlations for diverse classes of activators is discussed for the isozymes for which the phenomenon has been studied, i.e., CA I, II, III and IV. The possible physiological relevance of CA activation/inhibition is also addressed, together with recent pharmacological/ biomedical applications of such compounds in different fields of life sciences.

Abstract
The geometries of 19 biologically active substituted sulfonamides (including clinically useful acetazolamide, methazolamide, ethoxzolamide, dichlorophenamide, dorzolamide, and brinzolamide) in both neutral and deprotonated forms, were optimized using Becke3LYP/6-311+G(d,p) method (compounds 1-6) and two-layered ONIOM (B3LYP 6-311+G(d,p): MNDO) method (compounds 7-19). The investigated sulfonamides are weak acids with calculated acidity of about 1320-1420 kJ mol(-1). Of acids studied the highest gas-phase acidity (1324 kJ mol(-1)) possesses methazolamide. This drug is, according to the computed pKa value (5.9), also in water solution the most acidic compound of the sulfonamides investigated. The computed pKa values varied between 5.9 and 12.6 and correlate well with the available experimental pKa's found in the literature. Cancerostatic aromatic sulfonamides 16-19 are generally weak acids with the acidity comparable or slightly lower than the lead sulfanilamide. The available experimental partition coefficients of sulfonamides investigated are best reproduced by the IA LOGP method. Computed partition coefficients for antiglaucoma sulfonamides 1-13 varied between -0.47 and 2.61 (IA LOGP). Thus these compounds are only slightly or moderate lipophilic. The lipophilicity of the cancerostatic sulfonamides 14-18 is from relatively narrow interval between -0.07 and 1.68 (IA LOGP). The most potent CAI 10-13 are also the most lipophilic compounds among the antiglaucomatics studied. The available experimental solubilities are best reproduced by the IA LOGS method. The computed solubilities qualitatively correlate with the corresponding lipophilicities, logS increasing as logP declines. The analysis of molecular descriptors defined by Lipinski have been shown that all of the sulfonamides studied obey 'Rule of 5'. Therefore, in the early stages of the design of antiglaucoma sulfonamides, it is becoming more important to determine the pKa, lipophilicity, water solubility, and other physicochemical properties associated with a drug, before synthetic work is undertaken, with the aim of avoiding the synthesis of compounds that are predicted to have poor biopharmaceutical characteristics.

Abstract
At least 14 different carbonic anhydrase (CA, EC 4.2.1.1) isoforms were isolated in higher vertebrates, where these zinc enzymes play crucial physiological roles. Some of these isozymes are cytosolic (CA I, CA II, CA III, CA VII), others are membrane-bound (CA IV, CA IX, CA XII, and CA XIV), CA V is mitochondrial and CA VI is secreted in saliva. Three acatalytic forms are also known, which are denominated CA related proteins (CARP), CARP VIII, CARP X, and CARP XI. Several important physiological and physio-pathological functions are played by many CA isozymes, which are strongly inhibited by aromatic and heterocyclic sulfonamides as well as inorganic, metal complexing anions. The catalytic and inhibition mechanisms of these enzymes are understood in detail, and this helped the design of potent inhibitors, some of which possess important clinical applications. The use of such enzyme inhibitors as antiglaucoma drugs will be discussed in detail, together with the recent developments that led to isozyme-specific and organ-selective inhibitors. A recent discovery is connected with the involvement of CAs and their sulfonamide inhibitors in cancer: several potent sulfonamide inhibitors inhibited the growth of a multitude of tumor cells in vitro and in vivo, thus constituting interesting leads for developing novel antitumor therapies. Furthermore, some other classes of compounds that interact with CAs have recently been discovered, some of which possess modified sulfonamide or hydroxamate moieties. Some sulfonamides have also applications as diagnostic tools, in PET and MRI or as antiepileptics or for the treatment of other neurological disorders. Future prospects for drug design applications for inhibitors of these ubiquitous enzymes are also discussed.

Abstract
Bile acid amides (cholan-24-amides) of 5-substituted 1,3,4-thiadiazole-2-sulfonamide have been prepared from lithocholic, deoxycholic, cholic and dehydrocholic acids. Besides, the alcohol functional groups on the cholane ring systems were protected with acetyl group. Amides of the protected cholanes of lithocholic and cholic acids were also synthesized. Later, inhibition effects of these compounds on human carbonic anhydrase isozymes (HCA-I and II) have been investigated in vitro. For the most active compounds, inhibition constants ranged from 66 to 190nM for HCA-II with I(50) (molarity of inhibitor producing a 50% inhibition of CA activity). In addition, in vivo studies were performed for the synthesized compounds in Sprague-Dawley rats. The compounds (11 and 18) showed especially significant inhibition efficacy (p<0.001).

Abstract
Reaction of TBDMS-protected bile acids (cholic, chenodeoxycholic, deoxycholic, lithocholic, ursodeoxycholic acids) or dehydrocholic acid with aromatic/heterocyclic sulfonamides possessing free amino/hydroxy moieties, in the presence of carbodiimides, afforded after deprotection of the OTBDMS ethers, a series of sulfonamides incorporating bile acid moieties in their molecules. Many such derivatives showed strong inhibitory properties against three isozymes of carbonic anhydrase (CA, EC 4.2.1.1), that is CA I, II and IV, zinc enzymes playing critical roles in many pathologies, and which represent interesting targets for developing diverse pharmacological agents. Some of the most active derivatives, incorporating 1,3,4-thiadiazole-2-sulfonamide or benzothiazole-2-sulfonamide functionalities in their molecules, showed low nanomolar affinity for CA II and CAIV. Furthermore, the bioavailability of these derivatives in rabbits is comparable to that of acetazolamide, being in the range of 85-90%, showing them as promising candidates for systemically acting CA inhibitors.
