摘要:
A synthetic insulin mimetic compound is disclosed. Small synthetic amines of disaccharides, such as 2-deoxy-2-amino-galactopyranosyl pinitol are shown to mimic the action of insulin and to modulate its action.

Compounds are disclosed which have the formula (I) ##STR1## wherein R.sub.1 -R.sub.2 are each independently selected from the group consisting of: (a) a hydrogen atom; and (b) a lower alkyl group, straight or branched chain, having 1 to 8 carbon atoms; or R.sub.1 -R.sub.2 and the nitrogen atom to which they are bonded may together form a heterocyclic group; R.sub.3 -R.sub.10 are each independently selected from the group consisting of: (a) a hydrogen atom; (b) an alkyl group, straight or branched chain, having 1 to 24 carbon atoms; (c) a cycloalkyl group having 3 to 10 carbon atoms; (d) an alkenyl group, straight or branched chain, having 2 to 24 carbon atoms; (e) a cycloalkenyl group having 4 to 10 carbon atoms and one or more non-adjacent double bonds; (f) an aryl group having 6 to 10 carbon atoms; (g) an aralkyl group having 7 to 34 carbons atoms; (h) a heteroaryl group having 4 to 9 carbon atoms and at least one heteroatom selected from the group consisting of oxygen, nitrogen and sulfur; (i) a carboxyalkyl group, straight or branched chain, having 2 to 24 carbon atoms; (j) a carboxyaryl group having 7 to 34 carbon atoms; and (k) a heterocyclic group having 2 to 9 carbon atoms and at least one heteroatom selected from the group consisting of oxygen, sulfur and nitrogen; or any adjacent two of R.sub.3 -R.sub.10 may together form a cycloalkyl group or heterocyclic group; and X.sub.1 and X.sub.2 are each independently selected from the group consisting of an oxygen atom, a sulfur atom and a nitrogen atom. Pharmaceutical compositions containing these compounds and the use thereof for the treatment of disorders of glucose metabolism are also disclosed.
摘要:
A method for purifying two distinct insulin mediators to substantial homogeneity, and relative purity values above 80%, comprises adsorption on first anion exchange resin and subsequently on a chelex cation exchange resin column. The chelex resin ion exchange column substantially increases the activity of the recovered mediator. Following purification, the already treated fraction is subjected to three successive thin layer chromatography purification steps, the last giving, in the presence of ninhydrin stain, a characteristic salmon-color spot, which is indicative of the presence of the mediator. This process can also be used as a screening process, the absence of the salmon-colored spot being indicative of the diabetic state. Structure information on the insulin mediators obtained is given.
摘要:
A broadband communication system including an Internet Protocol Telephony Network and public switched telephone network, including apparatus and methods for placing a call on hold in a way that significantly reduces the amount of network bandwidth utilized by the call while the call is on hold. When a call is placed on hold, embodiments of the architecture of the telephony network of the present invention allows the network to essentially “forget” about the call placed on hold. In other words, a call that is on hold may require very little, or even zero, bandwidth within the telephony network. Accordingly, the total necessary bandwidth capacity of the telephony network may be smaller than it would be if calls on hold were to consume precious network bandwidth as is found in existing telephony systems.
