All-trans-retinol-d5 is a supplement that is used to protect the brain from oxidative damage and to help maintain healthy skin. It is an antioxidant that prevents free radicals from damaging cells and helps maintain the structural integrity of cell membranes. All-trans-retinol-d5 can be found in high concentrations in animal tissues, such as liver, lung, kidney, heart, brain, and eye. It can also be found in human urine. The presence of all-trans-retinol-d5 in urine has been correlated with neuroprotective effects. Retinol levels have been shown to be higher in children who are less obese than those who are obese or overweight. All-trans retinol has been shown to inhibit cancer cell proliferation and induce apoptosis by inhibiting protein synthesis at the level of transcription.

2-Carboxybenzoyl amlodipine is a metabolite of the antihypertensive drug amlodipine. It is a white crystalline solid that is soluble in water. 2-Carboxybenzoyl amlodipine can be used as an impurity standard for HPLC analyses, and as an analytical standard for the determination of amlodipine in human plasma.

2-Isopropyl-6-propylphenol is a reactive alkylating agent that reacts with proteins and enzymes. It binds to the hydroxyl group of a protein target, which modifies the activity of the target molecule by introducing a new functional group. 2-Isopropyl-6-propylphenol has been shown to bind to the active site of several enzymes, including human serum albumin and cytochrome P450 reductase. The binding constants for these targets have been determined computationally using an algorithm based on quantum chemical calculations. These values are in good agreement with experimental data obtained from titration calorimetry experiments at different temperatures.
