生物活性

XDS-23 is a selective biofilm inhibitor with an IC50 of 1.26 µM against Pseudomonas aeruginosa. XDS-23 exerts a dual inhibitory effect on the LasI/LasR System (las) and Pseudomonas Quinolone Signal System (pqs). XDS-23 suppress the production of key virulence factors including elastase, pyocyanin, and extracellular polysaccharides. XDS-23 exhibits synergistic antibacterial activity and can enhance the efficacy of multiple antibiotics in both in vitro and in vivo models, while maintaining a favorable safety profile. XDS-23 can be employed for research in combating biofilm-mediated drug-resistant P. aeruginosa infections[1].

体外研究
(In Vitro)

XDS-23 (0.3125-5 μM,24 小时) 可有效抑制铜绿假单胞菌 PAO1 生物膜的形成,使生物膜生物量减少高达 60% (5 µM 时) ,在不影响浮游菌生长的同时减少生物膜内存活细胞数量,并同步抑制胞外多糖合成 (5 µM 时抑制率达 50%),最终导致生物膜变薄且结构破坏[1]
XDS-23 (0.3125-5 μM,20 和 24 小时) 以浓度依赖性方式抑制绿脓菌素和弹性蛋白酶的生成,在 5 μM 浓度下对 PAO1 菌株的抑制率分别达 70% 和 50%[1]
XDS-23 (0.3125-5 μM,24 小时) 对临床耐药铜绿假单胞菌分离株具有广谱抑制活性,对多个菌株均表现出显著抑制效果,其中对 PA0617 和 PA1065 抑制率接近 50%,对 PA0808、PA1129、PA1074 和 PA1167 的抑制率分别为 44.87%、34.89%、33.56% 和 36.80%[1]
XDS-23 (0.3125-5 μM,20 小时) 可降低除 PA1031 外所有临床铜绿假单胞菌分离株中绿脓菌素的分泌,对 PA0808、PA0617 和 PA1074 菌株的抑制率超过 30%[1]
XDS-23 (0.3125-5 μM,24 小时) 主要通过抑制铜绿假单胞菌 PAO1 的 las 和 pqs 系统来减少生物膜形成和毒力因子产生[1]
XDS-23 (5 μM,24 小时) 以浓度依赖性方式抑制铜绿假单胞菌的运动能力:集群运动抑制率达 60% (5 μM),颤动运动抑制率为 50%,游动运动减弱 30%[1]
XDS-23 (0.3125-5 μM,24 小时) 在与 Polymyxin B (PMB) (HY-149179), Ciprofloxacin (CIP) (HY-B0356), Ceftazidime (CAZ) (HY-B0593),和 Tobramycin (Tob) (HY-B0441) 联用时,可降低铜绿假单胞菌 PAO1 的细菌负荷[1]
XDS-23 (6.25-100 μM,24 小时) 对人肝癌细胞 HepG2 无明显细胞毒性[1]
XDS-23 (1.25-40 μM,4 小时) 对兔红细胞无明显溶血活性[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
