Research Excerpts
Overview
Lipid X is a potential prototype compound for a new type of chemotherapy directed at blocking the harmful effects of LPS during bacterial septicemia. Lipid Y has the same structure as X, except for the additional presence of a palmitoyl moiety on the N-linked beta-hydroxymyristate.

Treatment
Excerpt | Reference | Relevance |
---|---|---|
"Treatment with lipid X and ticarcillin over a broad range of antibiotic dosages in 362 mice demonstrated improved survival of two- to fourfold (P less than 0.0001 at 24 h after inoculation, P less than or equal to 0.0005 at 48 h, and P less than or equal to 0.0001 at 5 days)." | ( Lipid X protects mice against fatal Escherichia coli infection. Craig, WA; Golenbock, DT; Leggett, JE; Proctor, RA; Raetz, CR; Rasmussen, P, 1988) | 2.06 |
Dosage Studied
The pharmacokinetic profile of lipid X was investigated in sheep and in two strains of mice by using 32P-labeled lipid X. Dose-response studies revealed that lipid X induced the production of smaller amounts of the tumor-cytotoxic factor than LPS at low concentrations. It induced that of considerable amounts at and over 1 microgram/ml.
