[Chpt 9] Then he entered into a ship and passed over and came into his own city. And lo, they brought to him a man sick of the palsy, lying in his bed. And when Jesus saw the faith of them, he said to the sick of the palsy: son be of good cheer, thy sins be forgiven thee. And behold certain of the Scribes said in themselves, this man blasphemeth. And when Jesus saw their thoughts, he said: wherefore think ye evil in your hearts? Whether is easier to say, thy sins be forgiven thee, or to say: arise and walk? That ye may know that the son of man hath power to forgive sins in earth, then said he unto the sick of the palsy: arise, take up thy bed, and go home to thine house. And he arose and departed to his own house. And when the people saw it, they marvelled and glorified God which had given such power to men. And as Jesus passed forth from thence, he saw a man sit a receiving of custom, named Matthew, and said to him: follow me. And he arose and followed him. And it came to pass as he sat at meat in the house: behold many Publicans and sinners came and sat down also with Jesus and his Disciples. When the Pharisees saw that, they said to his Disciples: why eateth your master with Publicans and sinners? When Jesus heard that, he said unto them: The whole need not the Physician, but they that are sick. Go and learn, what that meaneth: I have pleasure in mercy, and not in offering. For I not come to call the righteous, but the sinners to repentance. Then came the Disciples of John to him saying: why do we and the Pharisees fast oft: but thy Disciples fast not? And Jesus said unto them: Can the wedding children mourn as long as the bridegroom is with them? The time will come when the bridegroom shall be taken from them, and then shall they fast. No man pieceth an old garment with a piece of new cloth. For then taketh he away the piece again from the garment, and the rent is made greater. Neither do men put new wine into old vessels, for then the vessels break, and the wine runneth out, and the vessels perish. But they pour new wine into new vessels, and so are both saved together. While he thus spake unto them, behold there came a certain ruler, and worshipped him, saying: my daughter is even now deceased, but come and lay thy hand on her, and she shall live. And Jesus arose and followed him with his disciples. And behold a woman which was diseased with an issue of blood twelve years, came behind him and touched the hem of his vesture. For she said in herself: if I may touch but even his vesture only, I shall be safe. Then Jesus turned him about, and beheld her saying and tysabri.

At 1, 2, and 4 g ml, respectively. Although overall resistance rates for doxycycline, ampicillin-sulbactam, and cefoxitin were low 0.2, 2.8, and 6%, respectively ; , trovafloxacin was 4-, 8-, and 64-fold more active than these agents, respectively. Trovafloxacin was 64- and 8-fold more active than cefotetan and clindamycin, respectively. No strains were resistant to metronidazole; however, the trovafloxacin mode MIC was 4-fold less than that of metronidazole mode MIC, 0.25 versus 1 g ml ; Among the various species of the B. fragilis group, trovafloxacin was most active against strains of B. fragilis, B. thetaiotaomicron, B. distasonis, and B. ovatus MIC90s, 0.5 to 1 g while MICs among strains of B. uniformis and B. vulgatus were higher MIC90s, 4 g ml ; . comparisons of MIC90s among the various species, trovafloxacin was 4- to 32-fold more active than ciprofloxacin, 16- to 64-fold more active than cefoxitin, 32- to 256-fold more active than cefotetan, 2- to 32-fold more active than ampicillin-sulbactam, and 4- to 16-fold more active than clindamycin with the exception of B. uniformis strains ; . Trovafloxacin was more active than metronidazole against strains of B. fragilis, B. thetaiotaomicron, B. distasonis, and B. ovatus but was less active against B. uniformis and B. vulgatus. The activities of trovafloxacin against cefoxitin-resistant versus cefoxitin-susceptible B. fragilis group strains were virtually the same, inhibiting 92 versus 97% at 2 g ml and 100 versus 99.5% at 4 g ml, respectively. By comparison, the activities of cefotetan and ampicillin-sulbactam against cefoxitin-resistant strains were reduced. Interestingly, doxycycline was less active against cefoxitin-resistant strains. Additionally, the range of MICs for trovafloxacin among a group of B. fragilis group isolates with resistance to imipenem for which the MICs were 16 to 32 was similar to those of imipenem-susceptible strains. Trovafloxacin inhibited all strains of B. capillosus at 2 g ml, while all strains of P. bivia and P. disiens were inhibited at 1 and ubiquinone.

Structural modification to yield the corresponding benzenesulfonamide derivatives produces compounds with only one ionizable group in the biological pH range 3 ; . This charge difference was suggested to account for the better uptake into S. aureus for the sulfanilyl compounds. A role for target-mediated differences was discounted, because DNA supercoiling by E. coli gyrase was inhibited similarly by ciprofloxacin and its sulfanilyl homologues. However, given that topoisomerase IV is a primary target and gyrase is a secondary target for ciprofloxacin in S. aureus 9, 10, 22 ; , the influence of drug targeting on drug activity may be more complex than suggested by experiments with E. coli gyrase. Indeed, in the case of S. pneumoniae, where we have access to the relevant target enzymes, NSFQ105 and ciprofloxacin have differential activities against gyrase and topoisomerase IV in vitro Fig. 2 and 3 ; . It interesting to speculate on whether altered target specificity also contributes to enhanced potency in S. pneumoniae and S. aureus. Because we have focused exclusively on the determinants of quinolone target specificity, we do not know whether enhanced drug uptake influences sulfanilyl fluoroquinolone activity in S. pneumoniae. NSFQ-105 belongs to an expanding group of new quinolones that select gyrA QRDR mutants of S. pneumoniae in the first step. These agents include the archetype, sparfloxacin, and gatifloxacin 11, 25 ; . A second group of quinolones comprising ciprofloxacin, norfloxacin, levofloxacin, and trovafloxacin select parC QRDR changes in S. pneumoniae before gyrA QRDR changes 11, 15, 16, ; . There appears to be little cross-resistance between the drug classes when first-step gyrA or parC mutants are tested, consistent with the interpretation that the drugs act through different targets in vivo 11, 25 ; . Unfortunately, attempts to understand the structure-function relationships governing target preferences in vivo have been obfuscated by the multiple structural differences even between quinolones of the same class. Previously, we have suggested that the presence of a C-8 substituent is important in directing the quinolone to act through gyrase in vivo rather than through topoisomerase IV 26 ; . Although a role for C-8 is not excluded, the results reported here indicate unequivocally that a simple modification at C-7 of ciprofloxacin is sufficient to switch the drug from the topoisomerase IV-targeting class of agents to one that acts through gyrase. These findings are not restricted to ciprofloxacin. In a less detailed analysis, we have also examined C-7 benzenesulfonamide derivatives of norfloxacin akin to those of ciprofloxacin shown in Fig. 1. When we tested these derivatives against the panel of S. pneumoniae strains with defined resistance mutations Table 1 ; , we found that gyrA mutations increased resistance to NSFQ-104 the norfloxacin derivative equivalent to NSFQ-105 [2] ; , whereas a parC mutation had little effect data not shown ; . The opposite was seen for norfloxacin. These observations suggest that NSFQ-104 targets gyrase in S. pneumoniae, unlike norfloxacin, which is known to act through topoisomerase IV 11 ; . Thus, it appears that the C-7 substituent is an important factor governing target selection by quinolones in vivo. It remains to be established whether the C-7 substituent is the primary determinant of differential targeting or whether there is a complex series of structure-activity relationships, only one of which relates to substituents at C-7. In the absence of a crystal structure for a cleavable complex involving gyrase or topoisomerase IV, it is not presently possible to define in detail the molecular interactions that determine the target preferences of NSFQ-105 and ciprofloxacin in S. pneumoniae. However, our results can be considered in the context of a molecular model for the quinolone-gyrase-DNA complex proposed by Shen et al. 31 ; . According to this model.
