2-(3-Carboxy-3-(methylammonio)propyl)-L-histidine

[3-[[4-(2-amino-2-Carboxy-ethyl)-1H-imidazol-2-yl]]-1-carboxy- propyl]-methyl-ammonium

C11H19N4O4 (271.1406)

2-(3-Carboxy-3-(methylammonio)propyl)-L-histidine is an unusual amino acid that results from the post-translational modification of histidine in certain proteins. In particular, it is a post-translational derivative of histidine that exists in protein synthesis elongation factor 2 (EF2) at the site of diphtheria toxin-catalyzed ADP-ribosylation of elongation factor 2. It is a precursor for diphthamide. This compound is a substrate for the enzyme diphthine synthase (EC 2.1.1.98). This enzyme catalyzes the chemical reaction: S-adenosyl-L-methionine + 2-(3-carboxy-3-aminopropyl)-L-histidine = S-adenosyl-L-homocysteine + 2-[3-carboxy-3-(methylammonio)propyl]-L-histidine [HMDB] 2-(3-Carboxy-3-(methylammonio)propyl)-L-histidine is an unusual amino acid that results from the post-translational modification of histidine in certain proteins.

Bupranolol

1-(tert-butylamino)-3-(2-chloro-5-methylphenoxy)propan-2-ol

C14H22ClNO2 (271.1339)

Bupranolol is only found in individuals that have used or taken this drug. It is a non-selective beta blocker without intrinsic sympathomimetic activity (ISA), but with strong membrane stabilizing activity. Its potency is similar to propranolol:http://www.drugbank.ca/drugs/DB00571. Bupranolol competes with sympathomimetic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart, inhibiting sympathetic stimulation. This results in a reduction in resting heart rate, cardiac output, systolic and diastolic blood pressure, and reflex orthostatic hypotension.
