Bacterial growth associated with the use of biomedical indwelling devices can be combatted by the use of isothiazolones. An appropriate biomedical device comprises an elastomer having a Tg below 25°C having incorporated therein or coated thereon an effective amount of isothiazolone of the formula:
wherein Y is hydrogen, unsubstituted or substituted C4-C18 alkyl, unsubstituted or substituted C4-C18 alkenyl or alkynyl, an unsubstituted or substituted C3-C12 cycloalkyl, unsubstituted aralkyl of 6-10 carbon atoms, or unsubstituted or substituted aryl of 6-10 carbon atoms: R is hydrogen, halo, or C1-C4 alkyl; R' is hydrogen, halo, or C1-C4 alkyl. Generally therapeutically effective amounts are in the range 0.03 to 5 percent by weight isothiazolone based on elastomer.
使用异噻唑啉酮可以抑制与使用生物医学留置装置有关的细菌生长。一种合适的生物医学装置包括一种 Tg 低于 25°C 的弹性体,该弹性体中或其上涂有有效量的式中异噻唑啉酮:
其中Y是氢、未取代或取代的C4-C18烷基、未取代或取代的C4-C18烯基或炔基、未取代或取代的C3-C12环烷基、6-10个碳原子的未取代芳烷基或6-10个碳原子的未取代或取代芳基:R是氢、卤代或C1-C4烷基;R'是氢、卤代或C1-C4烷基。一般情况下,治疗有效量为异噻唑啉酮占弹性体重量的 0.03%至 5%。
