Abstract
Abstract A process is described for enhancing the immunogenic response of mammals. N-acylated-D-glucosamines were administered parenterally in the form of liposomes to mice at or before the time of administration of an immunogen or radiation, with the result that comparable or superior enhancement of the immune response was observed for these glycolipids when compared to LPS in assays measuring anti-SRBC or HGG hemagglutinin titers. The radiation protective effect of some of the synthetic adjuvants gave a definite protection, with up to 40% of lethally irradiated mice (700 R) surviving.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
52 words
The method of enhancing the immunogenic response of a mammal which comprises administering to a mammal parenterally before or at the time of administration of an immunogen a mixture of the immunogen and an effective amount of an N-acylated-D-glucosamine selected from the group consisting of N-lauroyl-D-glucosamine, N-myristoyl-D-glucosamine, N-stearoyl-D-glucosamine, N-palmitoyl-D-glucosamine, N-caprylyl-D-glucosamine and N-capryl-D-glucosamine.
Claim 2
Independent Claim
52 words
The method of enhancing the immunogenic response of a mammal which comprises administering to a mammal parenterally before or at the time of administration of an immunogen a mixture of the immunogen and an effective amount of an N-acylated-D-glucosamine selected from the group consisting of N-lauroyl-D-glucosamine, N-myristoyl-D-glucosamine, N-stearoyl-D-glucosamine, N-palmitoyl-D-glucosamine, N-caprylyl-D-glucosamine and N-capryl-D-glucosamine.
Claim 3
Dependent Claim

The method of claim 1 wherein the N-acylated-D-glucosamine is in the form of a liposome.
Claim 4
Independent Claim
43 words
