Forodesine (INN; also known as Immucillin H; trade names Mundesine and Fodosine) is a transition-state analog inhibitor of purine nucleoside phosphorylase [1] studied for the treatment of patients with T-cell acute lymphoblastic leukemia (T-ALL) and for treatment of B-cell acute lymphocytic leukemia (B-ALL).
Allergic sensitivity to quaternium-15 can be detected using a patch test. [7] It is the single most often found cause of allergic contact dermatitis of the hands (16.5% in 959 cases). [8] In 2005–06, it was the fourth-most-prevalent allergen in patch tests (10.3%). [9] Although quaternium-15 releases low amounts of formaldehyde. [10]
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F).

In the presence of a strong base such as KOH, the polymer/ring mixture is equilibrated, allowing complete conversion to the more volatile cyclic siloxanes: [10] [(CH 3) 2 SiO] 5n → n [(CH 3) 2 SiO] 5. where n is a positive integer. D 4 and D 5 are also precursors to the polymer. The catalyst is again KOH.
[11] [12] By 1959, the United States Army showed significant interest in deploying it as a chemical warfare agent. [10] It was originally designated "TK", but when it was standardized by the Army in 1961, it received the NATO code name "BZ", the Chemical Corps initially referred to BZ as CS4030, then later as EA 2277.
In 2023, more than five million Americans 12 and older reported a "prescription use disorder" within the past year, according to the Centers for Disease Control and Prevention (CDC).
7,12-Dimethylbenz[a]anthracene (DMBA) is an immunosuppressor and a powerful organ-specific laboratory carcinogen. [2] DMBA is widely used in many research laboratories studying cancer. DMBA serves as a tumor initiator. Tumor promotion can be induced with treatments of 12-O-tetradecanoylphorbol-13-acetate (TPA) in some models of two-stage ...
