US Patent:

20130197213, Aug 1, 2013

Filed:

Mar 14, 2013

Appl. No.:

13/826493

Inventors:

Stephen Craig Fields - Fishers IN, US

Assignee:

LEXINGTON PHARMACEUTICALS LABORATORIES, LLC - Carmel IN

International Classification:

C07H 1/00

US Classification:

536119, 536124

Abstract:

Disclosed is a method of chlorinating a carbohydrate or derivative thereof, for example, a sucrose-6-ester at the 4,1′, and 6′ positions, with irreversible removal of HCl formed during the reaction to form the chlorinated carbohydrate or derivative thereof, for example, a 4,1′,6′-trichloro-4,1′,6′-trideoxy-6-O-ester of galactosucrose (TGS-6E). The irreversible removal of HCl can be carried out by an irreversible physical process and/or an irreversible chemical process. Sucralose, an artificial sweetener, can be prepared by deesterification of the TGS-6E. The chlorination reaction takes place at low temperatures and the desired chlorinated product is obtained in high yields and in high purities.

US Patent:

20130197215, Aug 1, 2013

Filed:

Mar 14, 2013

Appl. No.:

13/826851

Inventors:

Stephen Craig Fields - Fishers IN, US

International Classification:

C07H 5/02

US Classification:

536122

Abstract:

Disclosed is a method for chlorinating a carbohydrate or a derivative thereof to produce a polychlorinated carbohydrate or a derivative thereof, such as sucralose, the method involves (i) reacting the carbohydrate or derivative thereof with a chlorinating agent to obtain a reaction mixture comprising said polychlorinated carbohydrate or derivative thereof and at least one under-chlorinated carbohydrate or derivative thereof, (ii) returning the at least one under-chlorinated carbohydrate or derivative thereof to a chlorinating step and further chlorinating the at least one under-chlorinated carbohydrate or derivative thereof to obtain the desired polychlorinated carbohydrate or derivative thereof; and (iii) optionally repeating steps (i) and (ii) “n” times where n≧1. The polychlorinated carbohydrate or a derivative thereof is obtained in high yields.

Inventors:

STEPHEN CRAIG FIELDS - Fishers IN, US

Assignee:

Lexington Pharmaceuticals Laboratories, LLC - Carmel IN

International Classification:

A61M 35/00

US Classification:

604290

Abstract:

The present invention discloses a novel medicinal roller ball applicator, comprising a ball with a rough surface, which can relatively painlessly facilitate the application and therapeutic massage of an active ingredient into a sensitive infected area of tissue for prolonged periods of time, while simultaneously removing dead epidermal tissue, a proven harrier to adsorption and penetration of active ingredients to the desired lower living skin tissue.
