Benzylamine is used as a masked source of ammonia, since after N-alkylation, the benzyl group can be removed by hydrogenolysis: [10] C 6 H 5 CH 2 NH 2 + 2 RBr → C 6 H 5 CH 2 NR 2 + 2 HBr C 6 H 5 CH 2 NR 2 + H 2 → C 6 H 5 CH 3 + R 2 NH. Typically a base is employed in the first step to absorb the HBr (or related acid for other kinds of ...
1-Phenylethylamine (1-PEA or α-PEA), also known as α-methylbenzylamine, is the organic compound with the formula C 6 H 5 CH(NH 2)CH 3. This primary amine is a colorless liquid is often used in chiral resolutions. Like benzylamine, it is relatively basic and forms stable ammonium salts and imines.
In childhood, T-cell acute lymphoblastic leukemia (T-ALL) patients can expect a 5-year event-free survival (EFS) rate of 70% and an overall survival (OS) rate of 80%. [1] Among the approximately 25% of children who relapse, survival rates drop to 30-50%, with patients generally showing a much poorer prognosis. [ 1 ]
lic 6 h 4 ch 2 n(ch 3) 2 + e + → 2-ec 6 h 4 ch 2 n(ch 3) 2 Via these reactions, many derivatives are known with the formula 2-X-C 6 H 4 CH 2 N(CH 3 ) 2 (E = SR, PR 2 , etc.). The amine is basic and undergoes quaternization with alkyl halides (e.g. hexyl bromide ) to give quaternary ammonium salts: [ 4 ]
While in-vitro studies showed that N-benzyl derivatives of 2C-I were significantly increased in potency compared to 2C-I, the N-benzyl derivatives of the related compound DOI were inactive. [60] 25B-NBOMe is a low-potency weak partial agonist of the rat and mouse trace amine-associated receptor 1 (TAAR1) but is inactive at the human TAAR1. [61]
Information on prognosis is limited by the rarity of the condition. Prognosis appears to be no different from AML in general, taking into account other risk factors. [9] [10] Acute erythroid leukemia (M6) has a relatively poor prognosis. A 2010 study of 124 patients found a median overall survival of 8 months. [10]
Acute promyelocytic leukemia is characterized by a chromosomal translocation involving the retinoic acid receptor alpha (RARA) gene on chromosome 17. [3] In 95% of cases of APL, the RARA gene on chromosome 17 is involved in a reciprocal translocation with the promyelocytic leukemia gene (PML) on chromosome 15, a translocation denoted as t(15;17)(q22;q21).

Methylenedioxybenzylamphetamine, abbreviated MDBZ, and systematically named 3,4-methylenedioxy-N-benzylamphetamine, is a psychedelic drug.It is the N-benzyl ...
