Delphinidin (chloride) is one of the common monomeric forms of anthocyanins, isolated from berries and red wine[1]. Delphinidin (chloride) induces apoptosis of HCT116 cells by regulating the functional status of JAK/STAT3 and MAPK signaling pathways[2]. Delphinidin (chloride) can block ERK pathway kinase phosphorylation and inhibit JNK signaling pathway activation[3].
In vitro, Delphinidin (chloride) (100μM) treatment of MSK cells for 24 hours effectively inhibits the repair of adenine adducts mainly induced by DBP[4]. Delphinidin (chloride) (10, 20 and 30μM) treatment of MDA-MB-231 cells for 22 hours effectively inhibits cell migration[5]. Delphinidin (chloride) (50μg/mL and 100μg/mL) treatment of triple-negative breast cancer cells (MDA231, MDA468) and HER2-overexpressing breast cancer cells (SKBR3, BT474) for 3-4 weeks significantly blocks their anchorage-independent growth and migration ability[6].
In vivo, oral administration of Delphinidin (chloride) (15mg/kg/day) to APP/PS1 model mice for 8 weeks can improve cognitive deficits in mice, reduce synaptic loss, and alleviate Aβ pathology[7]. Delphinidin (chloride) (50μg/kg/day) administered via intraperitoneal injection to hαSYN mice for 9 weeks can downregulate innate immune activity in mice, inhibit the activation of CD11b⁺ microglia, increase the number of anti-inflammatory CD8⁺ regulatory T cells, reduce dopaminergic neuron damage, restore striatal dopamine metabolism, and alleviate abnormal motor function in mice[8].
