US Patent:

41623037, Jul 24, 1979

Filed:

Jun 17, 1977

Appl. No.:

5/807654

Inventors:

Murray J. Sanders - Delray Beach FL

International Classification:

A61K 2900
A61K 3558
C12K 900

US Classification:

424 9

Abstract:

A method for proving the potency and atoxicity of modified neurotoxin is provided. A thin sheet of viable cells is provided on a growth substrate. Viability of the sheet of cells is defined as exhibiting an uninhibited growth potential of at least 10. sup. 6 Plaque Forming Units of Semliki Forest virus. The sheet of cells is treated with the test modified neurotoxin and then inoculated with the Semliki Forest virus. The reduction in the number of plaques of Semliki Forest virus in the culture indicates the potency of the modified neurotoxin, since the modified neurotoxin interferes with plaque formation by the Semliki Forest virus in proportion to its potency. Atoxicity of the modified neurotoxin is demonstrated by lack of cell destruction.

International Classification:

A61K 3558
A61K 3938

US Classification:

424 98

Abstract:

A method is provided for treatment of animals exposed to or subject to exposure to organophosphate animal poisonous nerve agents. The animals are injected with an effective amount of modified neurotoxin, preferably intramuscularly or intravenously, either prior to or shortly after exposure to the nerve agents. Particularly when the injection is administered prior to exposure, and where the dosage is of a higher amount, certain compositions achieve 100% survivors of Rhesus monkeys, even in the face of a challenge of 5 LD. sub. 50 of the nerve agent.

International Classification:

A61K 3558

US Classification:

424 98

Abstract:

The present invention relates to a composition, a process of production thereof, and a method for treatment of neurological diseases, and especially to the treatment of such diseases as amyotropic lateral sclerosis, by administering detoxified but neurotropically active modified snake venom neurotoxin composition derived from the venom of the Naja genus, where the composition exhibits at least a 30% inhibition of viral plaques in the Semliki Forest virus test and a bioassay shows the composition to be atoxic.
