CUR, Curcumin: Click to Expand ⟱
Features:
Curcumin is the main active ingredient in Tumeric. Member of the ginger family.Curcumin is a polyphenol extracted from turmeric with anti-inflammatory and antioxidant properties.
- Has iron-chelating, iron-chelating properties. Ferritin. But still known to increase Iron in Cancer cells.
- GSH depletion in cancer cells, exhaustion of the antioxidant defense system. But still raises GSH↑ in normal cells.
- Higher concentrations (5-10 μM) of curcumin induce autophagy and ROS production
- Inhibition of TrxR, shifting the enzyme from an antioxidant to a prooxidant
- Strong inhibitor of Glo-I, , causes depletion of cellular ATP and GSH
- Curcumin has been found to act as an activator of Nrf2, (maybe bad in cancer cells?), hence could be combined with Nrf2 knockdown

Clinical studies testing curcumin in cancer patients have used a range of dosages, often between 500 mg and 8 g per day; however, many studies note that doses on the lower end may not achieve sufficient plasma concentrations for a therapeutic anticancer effect in humans.
• Formulations designed to improve curcumin absorption (like curcumin combined with piperine, nanoparticle formulations, or liposomal curcumin) are often employed in clinical trials to enhance its bioavailability.

GLO-I, glyoxalase I: Click to Expand ⟱
Source:
Type:
GLO-I, or glyoxalase I, is an enzyme that plays a crucial role in the detoxification of reactive carbonyl species, particularly methylglyoxal, which is a byproduct of various metabolic processes.
-Glyoxalase-I (Glo-I) and glyoxalase-II (Glo-II) comprise the glyoxalase system and are responsible for the detoxification of methylglyoxal (MGO). MGO is formed non-enzymatically as a by-product, mainly in glycolysis, and leads to the formation of advanced glycation endproducts (AGEs).
-Elevated levels of GLO-I in cancer cells can help them cope with these toxic byproducts, promoting cell survival and proliferation.
-High levels of GLO-I may be associated with tumor progression and poor prognosis in certain types of cancer.
-Inhibiting GLO-I could sensitize cancer cells to chemotherapy and other treatments by increasing their vulnerability to oxidative stress.
-Many studies have reported that GLO-I is overexpressed in several types of cancers, including breast, lung, prostate, colorectal, and pancreatic cancers. This overexpression is often associated with aggressive tumor behavior and poor prognosis.
Inhibitors: – Several flavonoids such as quercetin, luteolin, and fisetin have been shown to inhibit glyoxalase I activity in enzyme assays. - Curcumin. - Resveratrol - EGCG
