Abstract

Royal jelly is the mixture of acids like 2-Decenoic acid (DA), 10-Hydroxy 2-Decenoic acid and many others. 10-HDA possesses strong inhibition to the growth of cancer cells, namely transferable AKR leukaemia, TA3 breast cancer, etc. The equilibrium geometry of 2-Decenoic acid and its derivative 10-Hydroxy 2-Decenoic acid in the ground state have been determined and analyzed by Density functional theory (DFT) employing 6-311 G (d, p) as the basis set. The harmonic frequencies of 2-DA and 10-HDA have also been calculated to understand its complete vibrational dynamics. The study of simulated spectra provides important information about the ability of the computational method to describe the vibrational modes.

Highlights

  • The chemical nature of the components of royal jelly has received considerable attention over the past 20 years

  • The main objective of the present study is to investigate in detail the vibrational spectra of important biological molecules (2-Decenoic acid and 10-Hydroxy 2-Decenoic acid) by Density functional theory (DFT) [12] method, which can presumably help in understanding its dynamical behavior

  • The optimized structure parameters and thermodynamic properties of the lowest energy conformer of 2-Decenoic acid and 10-Hydroxy 2-Decenoic acid were calculated by DFT/B3LYP levels with the 6-311 G (d, p) basis set and are listed in Tables 1 and 2, in accordance with the atom numbering scheme given in Figs 1 and 2

Summary

Introduction

The chemical nature of the components of royal jelly has received considerable attention over the past 20 years. It is a mixture of acids like 2-Decenoic acid, 10-Hydroxy 2-Decenoic acid and many others. 10-Hydroxy-2-Decenoic acid is a kind of special active substance which exists only in royal jelly in nature. It is called 10-HDA or royal jelly acid. The scientists mixed 10-HDA with active tumour cells taken from cancerous mice. They reported that an injection of the mixture suppressed mouse leukaemia and inhibited the formation of tumours. They reported that an injection of the mixture suppressed mouse leukaemia and inhibited the formation of tumours. 10-HDA has a strong antibacterial property, skin care, skin whitening and antioxidative activity effect. 10-HDA has other function including treatment of AIDS and other immunodeficiency diseases, insulin-like effect for diabetes and hypertension, antiulcer effects and preventive and therapeutic effects on hyperlipoidemia [3,6,14,19,20,21,23,25,26,27,28,29,30,31,32,33,34,35]
