Pexiganan (MSI 78 free base) is a synthetic analog of magainin 2. Pexiganan is a potent and orally active broad-spectrum antimicrobial peptide. Pexiganan can be used in the research of infections, such as diabetic foot ulcer infections[1].
Pexiganan (MIC: 0-128 μg/mL approximately) shows broad-spectrum antibacterial activity against 3,109 clinical isolates of gram-positive and gram-negative, anaerobic and aerobic bacteria[2].
Pexiganan (4 μg/mL) inhibits gastric ulcer strain and gastric cancer strain[3].
Pexiganan (1, 3, 10 or 30 mg/kg, p.o., daily for three consecutive days) shows H. pylori clearance efficiency in H. pylori-infected mouse[3].
Pexiganan (1 mg/kg, i.p.) shows antimicrobial activity in rat models of Gram-negative septic shock[4].
| Animal Model: | H. pylori-infected mouse[3]. |
| Dosage: | 1, 3, 10 or 30 mg/kg |
| Administration: | Oral administration, daily for three consecutive days. |
| Result: | Lowered H. pylori urease activities in mouse stomachs. |
| Animal Model: | Rat models of Gram-negative septic shock (induced by E.coli ATCC 25922)[4]. |
| Dosage: | 1 mg/kg |
| Administration: | Intraperitoneal injection (i.p.) |
| Result: | Displayed antimicrobial activities and survival rates of 67.7%. |

体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
