Usage

Description

Dehydroabietic acid (DHA or DAA) is an abietane diterpenoid, a monocarboxylic acid, and a carbotricyclic compound that is abieta-8,11,13-triene substituted at position 18 by a carboxy group. It is a resin acid commonly found in rosin and is derived from abietic acid. Dehydroabietic acid has a role as a metabolite and an allergen and is obtained from Pinus resin. It appears as a white solid or colorless needle crystal, slightly soluble in water, and soluble in methanol, ethanol, DMSO, and other organic solvents.

Uses

Used in Plastics Industry:
Dehydroabietic acid is used as a rosin-type nucleating agent for polypropylene (PP) to improve the polymer's properties and processing.
Used in Chemical Synthesis:
Dehydroabietic acid is commonly used in the synthesis of surfactants, antioxidants, and chiral catalysts, which are essential in various industrial applications.
Used in Analytical Chemistry:
Dehydroabietic acid serves as a reference standard for studying the aging process of Pinus resins using Fourier-transform infrared spectroscopy (FTIR) and for analyzing composition changes in Pinus genus with aging using Raman spectroscopy complemented with infrared spectroscopy.
Used in Environmental Studies:
Dehydroabietic acid is utilized to estimate resistance against biotic stress as a proxy in chemical defenses in Pinus halepensis, providing insights into the tree's ability to withstand environmental challenges.

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.

Synthesis of bodinieric acids A and B, both C-18 and C-19-functionalized abietane diterpenoids: DFT study of the key aldol reaction

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.

Late-stage C-H amination of abietane diterpenoids

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.

Syntheses of taiwaniaquinone F and taiwaniaquinol A via an unusual remote C-H functionalization

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.
