Cycloalkanes containing three or more hydroxyl groups on the ring atoms. Some polyhydroxypiperidines (PIPERIDINES) are called iminocyclitols or aza-sugars.

The preparation of new phosphorus-centered functional groups for modified oligonucleotides and other natural phosphates. (1/10)

Efforts to develop synthetic methodologies allowing the preparation of alpha,alpha- difluorophosphonothioates, alpha,alpha-difluorophosphonodithioates, alpha,alpha-difluorophosphono- trithioates, and alpha,alpha-difluorophosphinates are reviewed in the light of applications in the field of modified oligonucleotides and cyclitol phosphates. Two successful approaches have been developed, based either on the addition of phosphorus-centered radicals onto gem-difluoroalkenes or on a process involving the addition of lithiodifluorophosphono- thioates 91 onto a ketone and the subsequent deoxygenation reaction of the adduct. The radical route successfully developed a practical route to alpha,alpha-difluoro-H-phosphinates which proved to be useful intermediates to a variety of phosphate isosters. The ionic route led to the first preparation of phosphonodifluoromethyl analogues of nucleoside- 3'-phosphates.  (+info)

Hypoglycemic effect of 13-membered ring thiocyclitol, a novel alpha-glucosidase inhibitor from Kothala-himbutu (Salacia reticulata). (2/10)

A novel 13-membered ring thiocyclitol, isolated from an aqueous extract of Kothala-himbutu (Salacia reticulata), inhibited alpha-glucosidase in vitro. The inhibitory activity was investigated by maltose- and sucrose-loading on Wistar rats. This study found significant lowering of postprandial glucose levels, and the potency of 13-membered ring thiocyclitol was confirmed in vivo.  (+info)

Cyclitols are a type of sugar alcohol that consists of cyclic structures. Inositol is the most well-known cyclitol and is found in many foods, including fruits, beans, grains, and nuts. Other examples of cyclitols include D-pinitol and methyl-inositol. These compounds have been studied for their potential health benefits, such as improving insulin sensitivity and reducing inflammation. However, more research is needed to confirm these effects and establish recommended intake levels.
