Curcumin (Natural Yellow 3) is a phenolic natural product, an inhibitor of histone acetyltransferase p300/CREB (IC50=25 μM) with specificity. Curcumin has a wide range of pharmacological activities such as antitumor, anti-inflammatory and antioxidant.

Bisdemethoxycurcumin (Curcumin III) is a natural demethoxy derivative of curcumin. It is a potent activator of macrophage phagocytosis, interacting with 1α, 25-dihydroxy vitamin D3 to stimulate amyloid-β clearance by macrophages (optimal stimulation at 100 nM BDMC) [1]. More stable than curcumin in physiological media, BDMC suppresses proliferation of cancer cells [2]. It down-regulates the transcriptional coactivator p300, suppressing the Wnt/β-catenin pathway, and inhibits LPS induction of iNOS expression [3].

(1E,6E)-Bis(demethoxy)curcumin (Curcumin III) is a natural demethoxy derivative of curcumin,with anti-inflammatory and anti-cancer activities.

Tetrahydrocurcumin (HZIV 81-2), a major metabolite of curcumin, has strong antioxidant and cardioprotective properties.

1. Demethoxycurcumin (Desmethoxycurcumin) has antioxidant activity. 2. Demethoxycurcumin has anti-inflammatory activity. 3. Demethoxycurcumin has anti-proliferative activity. 4. Demethoxycurcumin has anti-acanthamoebic effect. 5. Demethoxycurcumin is a potential additive natural product in combination with chemotherapeutic agents in drug-resistant cancers. 6. Demethoxycurcumin inhibits energy metabolic and oncogenic signaling pathways through AMPK activation in triple-negative breast cancer cells.

Cyclocurcumin, a curcumin derivative, exhibits anticancer, anti-inflammatory, and immune-modulating abilities and is a potential compound for the treatment of rheumatoid arthritis as predicted by the MM-PBSA method. It may have a therapeutic potential as

Cyclobisdemethoxycurcumin exhibits antioxidant properties, demonstrated by its half maximal inhibitory concentrations (IC50s) of approximately 250 μM in the DPPH radical scavenging assay and 15-20 μM in the 2-DR oxidation assay [1].

Di-O-methyldemethoxycurcumin is a Curcumin analog isolated from medicinal plant turmeric di-orthomethyldemethoxycurcumin, anti-inflammatory and antioxidant properties Inhibition of IL-6 production, EC50 is 16.20μg/mL.

Tetramethylcurcumin is a novel curcumin analog, is an effective inhibitors of STAT3 phosphorylation, DNA binding activity, and transactivation in vitro.it also inhibits colony formation in soft agar, cell invasion, and exhibit synergy with the anti-cancer drug doxorubicin against breast cancer cells.

Dihydrocurcumin is the main metabolite of curcumin, which can reduce fat accumulation and oxidative stress response. Dihydrocurcumin can regulate the mRNA and protein expression levels of SREBP-1C, PNPLA3 and PPARα, increase the protein expression levels of pAKT and PI3K, and reduce the intracellular NO and ROS contents through Nrf2 signaling pathway.

5 -Methoxyhexahydrocurcumin is a natural product for research related to life sciences. The catalog number is TN5656 and the CAS number is 138870-96-9.

Octahydrocurcumin has antioxidant and and anti-inflammatory activities, it can inhibit the lipopolysaccharide (LPS)-induced inflammatory response via the mechanism of inhibiting NF-kB translocation to the nucleus. Octahydrocurcumin exhibits potent cytotoxic effect (IC50 =19.46 ug/mL) and shows high antimicrobial activity.

Hexahydrocurcumin is a selective, orally active COX-2 inhibitor and inactive against COX-1.

Dimethylcurcumin (ASC-J9) (ASC-J9) is an androgen receptor degradation enhancer. It effectively suppresses castration-resistant prostate cancer cell proliferation and invasion.

Demethoxycurcumin is found in Curcuma zedoaria and Etlingera elatior. It has a role as a metabolite, an antineoplastic agent and an anti-inflammatory agent.

3''-Demethylhexahydrocurcumin is a natural product for research related to life sciences. The catalog number is TN5760 and the CAS number is 881008-71-5.

κ-Carrageenan, a natural polymer found predominantly in red seaweeds, can serve as an effective drug carrier for delivering curcumin to cancer cells and inducing apoptosis. Additionally, κ-Carrageenan holds promise as a potential inflammatory agent, amplifying existing intestinal inflammation.
