Chemistry CF, SOzNHz was first synthesized in the laboratory of the Minnesota Mining and Manufacturing Company in 1956 23 ; . It white crystalline solid with a melting point at 117 "C. By titration with glass electrode the pK is 5.8. It is virtually unique among sulfonamides in being water soluble in the unionized form and is the most acidic sulfonamide known; pH of a 2% solution is 3.4. At neutral pH solutions are stable 1 for at least 1 month. At pH 3.4 and 1 the -SOZNHz group hydrolyzes with half-life of about 2 days. At 4-9 days 25% of activity remained and appeared at equilibrium, presumably with the corresponding sulfonic acid. More work is contemplated on this problem. Table I shows the inhibitory activity of CF3S02NH2against four isozymes of carbonic anhydrase, compared with four other sulfonamides and two inorganic anions. Their structures are given in Fig. 1. Broadly speaking except the total lack of reactivity of MK-417 against CA-I ; , the pattern of CF3SOZNHz similar to the is other sulfonamides, with activity in the order I1 I IV 111. Of special interest is that of the five sulfonamides tested, CF3SO2NH2 the smallest and is by far the most active against CA-111. This suggests that the resistance of CA-I11 to the sulfonamides may be due to the steric bulk of phenylalanine 198 nearthe active site 27 ; . The sulfonamide pattern is very different from the anion pattern, which shows inhibitor activity of 1 111 ; I1 IV ; . CF3SO2NHZis a stronger inhibitor Kr 2 nM ; than.

This method enables the comparison of solvation characteristics of a wide spectrum of compounds using quantitative thermodynamic parameters derived from experimental data. The objective may be to correlate these data to pharmacokinetic properties of drugs. heptanol ARG, lot 60K3706, Sigma and 1-octanol ARG, lot 11K3688, Sigma ; .

In 1911, Alzheimer discovered argyrophilic intraneuronal inclusions in similar cases and named these structures Pick bodies. In 1926, Pick's students Onari and Spatz coined the term Pick's disease to describe patients with frontotemporal atrophy and Pick bodies. Interest in this subject waned until the 1980s when groups in Manchester, England Neary et al., 1986 ; , and Lund, Sweden Brun, 1987; Gustafson, 1987 ; , rediscovered a dementia stemming from focal frontal atrophy. These groups found on microscopic examination that the characteristic changes of Alzheimer's disease were absent in their patients and that multiple histological pictures including Pick bodies in a minority of patients ; could be found in patients with frontal atrophy. The Lund and Manchester groups coined the term frontotemporal dementia FTD ; to describe the syndrome seen in these patients and developed clinical criteria for the diagnosis of this illness Brun et al., 1994; revised by Neary et al., 1998 ; . Mesulam 1982 ; renewed interest in cases of focal left temporal lobe atrophy with his description of primary progressive aphasia PPA ; , a dysfluent language disorder. Snowden et al. 1989 ; described a third frontotemporal syndrome, semantic dementia SD ; , a fluent language disorder marked by a loss of ability to appreciate word meaning and primarily associated with temporal lobe atrophy. More detailed descriptions of these three syndromes are available in Snowden et al. 1996 ; see Table 15.4.

The cell lysate showed both the 50-kDa P1 form and the 29-kDa M form, whereas the medium contained only the 29-kDa M form. PC6B and PC7 processed ADAMTS7PRO-CAT-Myc His, but the medium contained the 54-kDa Z form as well as the P1 and M forms, indicating that they inefficiently processed ADAMTS7 to its mature form. Interestingly, PACE4 showed predominantly the 54-kDa Z band in the medium, indicating a failure of this enzyme to utilize any of the furin sites within the prodomain of ADAMTS7. To ascertain which of the Arg60 and Arg220 furin sites was indispensable for zymogen maturation, we obtained site-directed mutants in which the P1 Arg residue was mutated to Ala. Expression of these forms in QBI 293A cells demonstrated that when Arg60 was mutated, processing occurred instead at an adjacent alternative site RVLR58 ; since a slightly decreased migration of the 50-kDa P1 band was noted Fig. 8C, lower panel, asterisk ; , and complete processing to the 29-kDa M form was also noted. On the other hand, when Arg220 was replaced by Ala, only the 50-kDa P1 band was noted, and the 29-kDa M form was absent in the medium. Although Nterminal sequence analysis suggests that Arg60 is preferred, these experiments suggest that when this site is unavailable, Arg58 can be used. Taken together, these data suggest a scenario in which furin is the preferred pro-ADAMTS7B convertase and that it may operate at two locations in the cell to sequentially produce the P1 and M forms. The data suggest that the processing event that produces the M form occurs at the cell surface through a 35-kDa intermediate. To further investigate this, we treated HEK293 cells expressing ADAMTS7PRO-CAT-Myc His with increasing concentrations of the synthetic furin inhibitor decanoyl-RVKR chloromethyl ketone. At low concentrations 10 M ; , it inhibited processing to the 35-kDa intermediate and the M form, but only partially inhibited processing to the 50-kDa form Fig. 8D ; . Since this lipophilic inhibitor will permeate cells, higher concentrations 25 M ; completely inhibited processing to the P1 and smaller forms, and only the zymogen was apparent Fig. 8D ; . ADAMTS7B and ADAMTS7PRO-CAT-Myc His Are Functional Proteinases--ADAMTS7B was demonstrated to be catalytically active using the broad-spectrum protease substrate and inhibitor 2-macroglobulin 32 ; . 2-Macroglobulin, a serum protein, is a circulating endoproteinase inhibitor that is commonly used as a nonspecific protease substrate. Cleavage by many proteases within a proteolytically susceptible "bait" region results in engulfment of the protease and is frequently followed by formation of an irreversible complex. Thus, anomalous migration of a protease upon incubation with 2-macroglobulin is considered evidence of proteolytic activity. ADAMTS7PRO-CATMyc His and ADAMTS7B were both able to cleave 2-macroglobulin as shown by altered migration of the protease on SDSpolyacrylamide gel Fig. 9, A and B ; and proteolysis of 2macroglobulin by SDS-PAGE Fig. 9C ; . However, using antineoepitope antibodies to detect specific ADAMTS cleavage products of aggrecan and versican 12, 33 ; , ADAMTS7B digestion did not reveal the target epitopes data not shown ; , suggesting that it does not attack these sites. In these experiments, equivalent amounts of ADAMTS7B that cleaved 2macroglobulin were used. ADAMTS7B-transfected cells did not process aggrecan either, whereas ADAMTS4-transfected cells did, despite the ADAMTS7 expression level being considerably higher compared with the ADAMTS4 expression level Fig. 9D ; . In combination, these studies demonstrate that ADAMTS7B could not process aggrecan in cells even at much higher levels compared with ADAMTS4 and in solution at levels at which it could cleave 2-macroglobulin.

MMWR. 2004; 53: 100-103 table omitted SINCE MID-DECEMBER 2003, EIGHT ASIAN countries Cambodia, China, Indonesia, Japan, Laos, South Korea, Thailand, and Vietnam ; have reported an epizootic of highly pathogenic avian influenza in poultry and various other birds caused by influenza A H5N1 ; . As of February 9, 2004, a total of 23 laboratory-confirmed human cases of influenza A H5N1 ; had been reported in Thailand and Vietnam. In 18 78% ; of these cases, the patients died. Clinical experience with avian H5N1 disease in humans is limited.1 The human H5N1 viruses identified in Asia in 2004 are antigenically and genetically distinguishable from the 1997 and February 2003 viruses. To aid surveillance and clinical activities, this report provides a preliminary clinical description of the initial five confirmed cases in Thailand. Of the five laboratory-confirmed cases in Thailand, four were in male children aged 6-7 years, and one was in a female aged 58 years; all patients were previously healthy. Four patients reported deaths in poultry owned by the patient's family, and two patients reported touching an infected chicken. One patient had infected chickens in his neighborhood and was reported to have played near a chicken cage. None of the confirmed cases occurred among persons involved in the mass culling of chickens. Patients reported to hospitals 2-6 days after onset of fever and cough. Other early symptoms included sore throat four ; , rhinorrhea two ; , and myalgia two ; . Shortness of breath was reported in all patients 1-5 days after symptom onset. On admission, clinically apparent pneumonia with chest radiograph and fosamprenavir.
