Isolation of 6-gingerol and semi-synthesis of 1,4-benzodiazepines derivatives: An in-situ pharmacokinetics properties, molecular docking and molecular dynamics simulation assessments

This paper outlines a methodical approach for isolating 6-gingerol (1a) from Zingiber officinale Roscoe rhizomes on a gram-scale, resulting in a product of high purity and significant yield. Further, 6-gingerol (1a) [SSG1] derivatives, including 1-(4-hydroxy-3-methoxyphenyl)decane-3,5-dione (1ab), were synthesized via a semi-synthetic pathway involving DMP-mediated fast oxidation and replication. Subsequently, a new series of 1,4-benzodiazepines (3a-c) was synthesized quantitatively using a basic technique. This synthesis necessitated the interaction of 1ab with various o-phenylenediamine (2a-c) compounds. Spectroscopic methods were employed to characterize the synthesized 1,4-benzodiazepines (3a-c)[SSG2, SSG3 & SSG4]. Despite extensive investments by pharmaceutical companies in traditional drug research and development for diseases like type 2 diabetes (T2D), successful treatments remain elusive. Medication repurposing has gained traction as a strategy to address not only diabetes but also other disorders. Leveraging existing molecular pharmacology data accelerates the development of new medications. This paper underscores the importance of repurposing traditional medicines to combat a range of communicable and non-communicable diseases, offering a promising avenue for therapeutic advancement. Additionally, molecular docking studies suggested that one derivative (SSG2) exhibited stronger binding affinity compared to the reference standards. Overall, the findings of this study highlight the potential of semi-synthetic gingerol derivatives for the development of novel therapeutic agents.
