Abietic acid (AA), a diterpene produced by conifer species, such as grand fir and lodgepole pine, has been reported to have anti-inflammatory and immunomodulatory effects and can be used as a wound-healing agent. Its treatment elevates cell migration and tube formation in human umbilical vein vascular endothelial cells by the activation of ERK and p38 MAPKs. In addition was shown, that abietic acid could be used as an antimetastatic agent or as an adjuvant for anticancer therapy. AA acts as a PPARα/γ dual activator to inhibit age-related inflammation by suppressing NF-κB and the MAPK/AP-1 pathway and can be a useful agent for improving skin photoaging.

p-Toluenesulfonic acid (PTSA) is an organic compound with the formula CH3C6H4SO3H. An aromatic sulfonic acid, often used as a strong acid catalyst. p-Toluenesulfonic acid monohydrate has been used as a reducing agent for the reductive amination of ketones and aldehydes. In the presence of p-Toluenesulfonic acid monohydrate novel deazaflavin-cholestane hybrid compounds have been synthesized in a condensation reaction. 2-Phenylethyl alpha-glucoside has also been synthesized in the presence of p-Toluenesulfonic acid monohydrate. p-toluenesulfonic acid esters, are a common class of reagents used in the pharmaceutical industry as alkylating agents, catalysts, and in purification steps of the chemical synthesis of a drug substance.
