Biological Activity

L-Thyroxine is a synthetic form of thyroxine and a hormone replacement compound. L-Thyroxine (T4) and Triiodothyronine (T3) hormones are known to modulate the expression of ionic channels, pumps and regulatory contractile proteins. Moreover, thyroid hormones have been shown to influence calcium homeostasis and flux responsible for excitation and contractility, with L-Thyroxine and Triiodothyronine modulating its pharmacological control and secretion. In rats fed 12 weeks with the iodine-free diet, a significant decrease in the levels of both Triiodothyronine and L-Thyroxine is observed when compared to the control group fed with standard diet (p<0.001). In the group treated with low doses of L-Thyroxine, an increase in L-Thyroxine levels is observed (p=0.02) while Triiodothyronine levels remain virtually similar to the control group (p=0.19).

6α-Hydroxy Paclitaxel

6α-Hydroxy Paclitaxel is a primary metabolite of Paclitaxel. 6α-Hydroxy Paclitaxel (6-Hydroxytaxol) retains a time-dependent effect on organic anion-transporting polypeptides 1B1/SLCO1B1 (OATP1B1) with similar inhibition potency to Paclitaxel, whereas it no longer showed time-dependent inhibition of OATP1B3.

Casein (from bovine milk)

Casein is a phosphorus-containing complex protein with α-casein and β-casein as its main components. Casein is an orally active phosphoprotein that can be separated into various electrophoretic components, such as α2-Casein, κ-Casein, β-casein, and γ-casein. Casein can be used in biochemical research, to formulate biological culture media, and as a thickener, emulsifier and stabiliser.

Palmitic acid-13C16

Palmitic acid-13C16 is the 13C-labeled Palmitic acid. Palmitic acid is a long-chain saturated fatty acid commonly found in both animals and plants.

Methionine sulfoximine

Methionine sulfoximine (2-Amino-4-(S-methylsulfonimidoyl)butanoic acid) is an irreversible inhibitor of glutamine synthetase. Methionine sulfoximine is able to affect the metabolism of glutamate and glutamine.

L-Glutamine-15N2

L-Glutamine-15N2 is the 15N-labeled L-Glutamine. L-Glutamine is a non-essential amino acid present abundantly throughout the body and involved in many metabolic processes. L-Glutamine provides a source of carbons for oxidation in some cells.
