surfactants, antioxidants and chiral catalysts.
Definition
ChEBI: Dehydroabietic acid is an abietane diterpenoid that is abieta-8,11,13-triene substituted at position 18 by a carboxy group. It has a role as a metabolite and an allergen. It is an abietane diterpenoid, a monocarboxylic acid and a carbotricyclic compound. It derives from an abietic acid. It is a conjugate acid of a dehydroabietate.
Application
Dehydroabietic acid (DHA or DAA) is a bioactive phytochemical, diterpenoid found in various Pinus species. It is a resin acid and a derivative of abietic acid (AA).Dehydroabietic acid has been used as a reference standard:to study the aging process of Pinus resins using Fourier-transform infrared spectroscopy (FTIR)to study the composition changes in Pinus genus with aging using Raman spectroscopy complemented with infrared spectroscopyto estimate resistance against biotic stress as proxy in chemical defenses in Pinus halepensis
Biochem/physiol Actions
Dehydroabietic acid (DHA) exerts various biological activities such as anti-cancer, anti-aging, antimicrobial, antiulcer, gastroprotective, and cytotoxic activities. It is a potent anti-inflammatory agent and a dual activator of peroxisome proliferator-activated receptors alpha and gamma (PPAR α/γ). DHA has an anti-aging effect and a sirtuin 1 (SIRT1) activating compound. It has antibacterial properties against multidrug-resistant strains. dehydroabietic acid and its derivatives have gastroprotective and cytotoxic effects.
Check Digit Verification of cas no
The CAS Registry Mumber 1740-19-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,4 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1740-19:
(6*1)+(5*7)+(4*4)+(3*0)+(2*1)+(1*9)=68
68 % 10 = 8
So 1740-19-8 is a valid CAS Registry Number.

Synthesis of bodinieric acids A and B, both C-18 and C-19-functionalized abietane diterpenoids: DFT study of the key aldol reaction
González-Cardenete, Miguel A.,Zaragozá, Ramón J.
, p. 15015 - 15022 (2020/04/27)
The first synthesis of C-18- and C-19-bifunctionalized abietane diterpenoids, bodinieric (or callicapoic) acids, via an aldol reaction has been developed. This key aldol reaction was very sensitive to steric hindrance. This fact has been studied by deuterium exchange experiments and DFT methods. Optimization of this reaction led to the synthesis of anti-inflammatory bodinieric acids A and B, starting from abietic acid.

This study aims at highlighting the synthetic versatility of the rhodium-catalyzed C-H amination reactions using iodine(iii) oxidants for the late-stage functionalization of natural products. Inter-and intramolecular nitrene insertions have been performed from various abietane diterpenoids, leading to the amination of the C-3, C-6, C-7, C-11 and C-15 positions. Ca. 20 aminated compounds have been isolated with yields of up to 86% and high levels of regio-, chemo-and stereoselectivities.

A protecting-group-free route to (-)-taiwaniaquinone F based on a ring contraction and subsequent aromatic oxidation of a sugiol derivative is reported. In addition, the first synthesis of (+)-taiwaniaquinol A is reported via short time exposure of (-)-taiwaniaquinone F to sunlight triggering a remote C-H functionalization. The hypothesis that the biogenesis of some methylenedioxy bridged natural products could proceed via similar nonenzymatic mechanisms is presented.
