The present invention provides cells having more than two drug resistance genes and at least two different resistance genes that have been recombined into the chromosome of a cell. It also teaches the processes for preparing cells by recombining two or more different drug resistance genes into the chromosome of a cell. The invention further shows a screening method using the cells of described herein that may be used to accomplish high throughput screening of, among other things, natural products and/or whole cells isolated from the environment.

A urethral catheter composed of olefin polymer, diene polymer or silicone polymer as a base material wherein an antimicrobial substance being chemically bonded with the inside wall and/or the outside wall thereof, and a process for producing the same. This urethral catheter effectively prevents urinary tract infection for a long period of time.
Disclosed are KS-501 derivatives represented by the formula (I)
wherein X represents a hydrogen atom or COOR₃, Y represents hydroxy or
and R₁, R₂ and R₃ are the same or different and represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, provided that when R₁, R₂ and R₃ are simultaneously hydrogen atoms, and when R₁, R₂ and X are simultaneously hydrogen atoms, Y does not represent
and a pharmaceutically acceptable acid addition salt thereof. The KS-501 derivatives have a platelet aggregation-inhibiting property, and are expected to be useful as antithrombotic agent.
