Application of 100361-18-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 100361-18-0, 7-Chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic Acid, introducing its new discovery.

A series of the R and S isomers of 7-[3-(1-amino-1-methylethyl)-1- pyrrolidinyl]-1,4-dihydro-4-oxoquinoline- and 1,8-naphthyridine-3-carboxylic acids was prepared to determine the effect on potency of the two methyl groups adjacent to the distal nitrogen in the pyrrolidinyl moiety. The antibacterial efficacy of these dimethylated derivatives was compared to the relevant 7-[3-(aminomethyl)-1-pyrrolidinyl] parent compounds and, to a lesser extent, the 7-[3-(1-aminoethyl)-1-pyrrolidinyl] analogues. The activity of the title and reference compounds was assayed in vitro using an array of Gram-negative and Gram-positive organisms and in vivo using a mouse infection model. Selected derivatives were then screened for potential side effects in a phototoxicity mouse model and an in vitro mammalian cell cytotoxicity protocol. The results showed that the R isomer displayed a 2-20-fold advantage in activity in vitro and a 2-15-fold advantage in vivo over the S isomer. Although equipotent to the 7-[3-(aminomethyl)-1-pyrrolidinyl] parent compounds in vitro, the R isomers of the 7-[3-(1-amino-1-methylethyl)-1- pyrrolidinyl] analogues showed a dramatic increase in in vivo potency, especially via the oral route of administration. These same R isomers also appeared to possess a reduced risk of phototoxicity and cytotoxicity. This combination of superior in vivo performance with a low degree of phototoxicity and mammalian cell cytotoxicity recommends these agents for further study. Of these agents, naphthyridine 16-R represents the optimal blend of potency and safety.

A series of stereochemically pure 7-<3-(1-aminoethyl)-1-pyrrolidinyl>-1,4-dihydro-4-oxoquinoline and 1,8-naphthyridine-3-carboxylic acids, with varied substituents at the 1-, 5-, and 8-positions, were synthesized to study the effects of the 7-<3-(1-aminoethyl)-1-pyrrolidinyl> moiety on potency and in vivo efficacy relative to the known 7-<3-(aminomethyl)-1-pyrrolidinyl> derivatives. The antibacterial efficacies of the target compounds and their relevant reference agents were determined in vitro using an assortment of Gram-negative and Gram-positive organisms and in vivo using Escherichia coli and Streptococcus pyogenes mouse infection models. The effects of the 7-<3-(1-aminoethyl)-1-pyrrolidinyl> moiety were also examined at the level of the target enzyme by employing a DNA-gyrase supercoiling inhibition assay. Selected compounds were further evaluated for potential phototoxic and clastogenic liabilities using a phototoxicity mouse model and an in vitro mammalian cell cytotoxicity assay. It was found that the differences in in vitro antibacterial activity between the stereoisomers were significantly greater than previously reported for other optically pure 3-substituted pyrrolidinyl side chains. Relative to their 7-<3-(aminomethyl)-1-pyrrolidinyl> analogs, the (3R,1S)-3-(1-aminoethyl)pyrrolidines generally conferred a 2-4-fold increase in Gram-positive in vitro activity and an average of 10-fold improvement in oral efficacy. The level of phototoxicity and cytotoxicity of the product quinolones was ultimately determined by the combined influence of the 7-<3-(1-aminoethyl)-1-pyrrolidinyl> side chains and the other quinolone substituents. From this study, several compounds were identified with outstanding antibacterial activity and low degrees of phototoxicity and mammalian cell cytotoxicity. One such agent, 34F-R,S (PD 140248), showed the best overall blend of safety and efficacy.
