HIF-1α-IN-2 hydrochloride is a potent HIF-1α inhibitor exhibiting anticancer activity, demonstrated by IC50 values of 28 nM in MDA-MB-231 cells and 15 nM in MiaPaCa-2 cells. It effectively suppresses HIF-1α expression by inhibiting both transcription and protein translation [1].

VHL-IN-1 (compound 30), a ubiquitin E3 ligase von Hippel-Lindau (VHL) inhibitor with a dissociation constant (Kd) of 37 nM, potently stabilizes HIF-1α and enhances its transcriptional activity. It shows promise for applications as a HIF-1α stabilizer and for the degradation of proteolytically targeted chimeras (PROTACs) [1].

PHD-IN-2 (Compound 91), a potent PHD antagonist with an IC50 of less than 5 nM, effectively stimulates erythropoietin synthesis in HEP3B cells with an EC50 of less than 2.5 μM. It is applicable for research purposes across various medical fields, including cardiovascular, metabolic, hematological, pulmonary, kidney, liver, and wound healing disorders, as well as cancer [1].

Hydroxycitric acid tripotassium hydrate (Potassium citrate monohydrate) effectively inhibits stones formation and also inhibits HIF, and has antioxidation, anti-inflammation, and anti-tumor effects. Hydroxycitric acid tripotassium hydrate(Potassium citrate monohydrate) (Potassium citrate monohydrate) is the major active ingredient of Garcinia cambogia and a derivative of citric acid. Hydroxycitric acid tripotassium hydrate(Potassium citrate monohydrate) competitively inhibits ATP citrate lyase with weight loss benefits.

SYP-5 is a novel inhibitor of HIF-1, suppresses tumor cells invasion and angiogenesis.
