Paragraph 0083-0088; 0133, (2019/12/25)
Disclosed is a method for preparing a chiral Gingerol compound. To prepare the chiral Gingerol compound, a racemic Gingerol compound is treated with kinetic resolution in the presence of a chiral catalyst compound and an alkali metal fluoride so a chiral Gingerol compound with high optical purity can be prepared. An oligo ethylene glycol-derived compound including an oligo ethylene glycol functional group, a basic part, and a hydroxy functional group of a binol derivative, an acidic part, can be used as a chiral catalyst compound.COPYRIGHT KIPO 2020

Pseudomonas aeruginosa is a causative agent of chronic infections in immunocompromised patients. Disruption of quorum sensing circuits is an attractive strategy for treating diseases associated with P. aeruginosa infection. In this study, we designed and synthesized a series of gingerol analogs targeting LasR, a master regulator of quorum sensing networks in P. aeruginosa. Structure-activity relationship studies showed that a hydrogen-bonding interaction in the head section, stereochemistry and rotational rigidity in the middle section, and optimal alkyl chain length in the tail section are important factors for the enhancement of LasR-binding affinity and for the inhibition of biofilm formation. The most potent compound 41, an analog of (R)-8-gingerol with restricted rotation, showed stronger LasR-binding affinity and inhibition of biofilm formation than the known LasR antagonist (S)-6-gingerol. This new LasR antagonist can be used as an early lead compound for the development of anti-biofilm agents to treat P. aeruginosa infections.

A straightforward synthesis of (S)-gingerols 1-3 has been described. The requisite stereogenic center in the target molecules was introduced by Sharpless asymmetric dihydroxylation using a chiral complex, AD-mix β. This route is simple and efficient to prepare the products in very good yields.

An enantioselective approach to (+)-(S)-[n]-gingerols (1a-c) has been developed. The requisite stereogenic centers of target molecules are facilely constructed by the proline-catalyzed cross-aldol reaction from readily available achiral starting materials
