The syntheses of a series of (aralkylamino)- and (alkylamino)benzoic acids, as well as the corresponding esters and sodium salts, are described. The compounds were evaluated in vivo in rats for serum sterol and triglyceride lowering activity and in vitro for activity in inhibiting the principle cholesterol-esterifying enzyme of the arterial wall, fatty acyl-CoA:cholesterol acyltransferase (ACAT). Based on a combination of these two activities, cataben sodium (150) was selected for development as a hypolipidemic and potential antiatherosclerotic agent.

Sepsis-induced acute kidney injury (SI-AKI) is the most common organ dysfunction of sepsis, characterized with prolonged hospitalization periods and significantly elevated mortality rates. Piplartine (PLG), an alkaloid extracted from Piper longum within the Piperaceae family, has exhibited diverse pharmacological activities, including anti-inflammatory, anti-atherosclerotic, and anti-tumor effects. Herein, we investigated whether the PLG could reverse SI-AKI and explore its possible anti-inflammatory mechanisms.

Atherosclerosis (AS) is a chronic inflammatory vascular disease and the primary pathological basis of cardiovascular diseases. Epigallocatechin-3-gallate (EGCG), the most abundant polyphenol compound in green tea, has garnered significant attention in recent years for its protective effects against AS. EGCG possesses properties that lower lipid levels, exhibit antioxidant and anti-inflammatory activities, enhance plaque stability, and promote the recovery of endothelial function.

Atherosclerosis (AS) is a prevalent cardiovascular condition, and the growth and phenotypic switch of vascular smooth muscle cells (VSMCs) play a crucial role in its development. Studies have revealed that the activation of certain transcription factors and signaling pathways can trigger these cellular changes. Consequently, targeting these pathways and pivotal molecules has emerged as a promising strategy for AS treatment.

Atherosclerosis is a primary cause of cardiovascular disease, straining healthcare systems. Dendrobium officinale, a widely used food-medicine homology, has demonstrated anti-atherosclerotic (anti-AS) properties, with other species listed in pharmacopoeias exhibiting similar effects. However, their efficacy varies, and the impact of interspecies variations on compounds and mechanisms in Dendrobium's anti-AS effects remains unclear.
