Notarnicola A, Tamma R, Moretti L, Panella A, Dell'endice S, Zallone A, Moretti B. Effect of shock wave treatment on platelet-rich plasma added to osteoblast cultures. ULTRASOUND IN MEDICINE & BIOLOGY 2011; 37:160-168.

Abstract
The aim of this study was to verify the effects on osteoblast cultures of adding a platelet-rich plasma (PRP) concentrate pretreated with 500 shock wave (SW) at an energy flow density of 0.17 mJ/mm(2), emitted by an electromagnetic generator Minilith SL1 (STORZ, Germany), reproducing the conditions of our previous study in which we apply SW directly on osteoblasts. Real-time PCR showed that in osteoblast cultures with added PRP pretreated with SW, there was an increased expression at 48 h of insulin-like growth factor binding protein 3 (IGFBP-3) and runt-related transcription factor 2 (RUNX2) and at 72 h, of collagen type I, osteocalcin, insulin-like growth factor 1 (IGF-1) as well as IGFBP-3. Western blotting confirmed the increased protein synthesis of IGFBP-3. This experience suggests that extracorporeal shock wave treatment (ESWT) should stimulate osteogenesis also by indirect platelets-mediated network. It therefore seems possible that combining the two methods, ESWT and bioengineering procedures to infiltrate PRP and growth factors, could be a successful approach.

Abstract
Cysteamine (1) was reported many years ago to reversibly inhibit lentil seedling amine oxidase, through the formation of a complex with thioacetaldehyde, the turnover product of 1. Herein, cysteamine (1) and its analogs 2-(methylamino)ethanethiol (3) and 3-aminopropanethiol (6) were found to be reversible inhibitors of bovine plasma amine oxidase (BPAO), but 2-(methylthio)ethylamine (7) was determined to be a weak irreversible inhibitor of BPAO. Based on our results, indicating the necessity of a sulfhydryl-amine for reversible inactivation of BPAO, the failure of inhibited BPAO to recover activity after gel filtration, the first-order kinetics of activity recovery upon dialysis, and 2,4,6-trihydroxyphenylalanine quinine (TPQ) cofactor transformation which indicated from the results of phenylhydrazine titration and substrate protection, we propose a mechanism for the reversible inactivation of BPAO by 1 involving the formation of a cofactor adduct, thiazolidine, between BPAO and 1.

Abstract
LSD1 is a flavin-dependent histone demethylase that oxidatively removes methyl groups from Lys-4 of histone H3. LSD1 belongs to the amine oxidase enzyme superfamily which utilize molecular oxygen to transform amines to imines that are hydrolytically cleaved to formaldehyde. In prior studies, it has been shown that monoamine oxidase inhibitory scaffolds such as propargylamines and cyclopropylamines can serve as mechanism-based inactivators of LSD1. Propargylamine-histone H3 peptide analogues are potent LSD1 inhibitors, whereas small molecule antidepressant MAO acetylenic inhibitors like pargyline do not inhibit LSD1. In contrast, the small molecule MAO cyclopropylamine inhibitor tranylcypromine is a time-dependent LSD1 inhibitor but exo-cyclopropylamine-peptide substrate analogue is not. To provide further insight into small molecule versus peptide relationships in LSD1 inhibition, herein we further our analysis of warheads in peptide scaffolds to include the chlorovinyl, endo-cyclopropylamine, and hydrazine-functionalities as LSD1 inactivators. We find that chlorovinyl-H3 is a mechanism-based LSD1 inactivator whereas endo-cyclopropylamine-H3 does not show time-dependent inactivation. The hydrazine-H3 was shown to be the most potent LSD1 suicide inhibitor yet reported, more than 20-fold more efficient in inhibiting demethylation than propargylamine-H3 derivatives. We re-explored MAO antidepressant agent phenelzine (phenethylhydrazine), previously reported to be a weak LSD1 inhibitor, and found that it is far more potent than previously appreciated. We show that phenelzine can block histone H3K4Me demethylation in cells, validating it as a pharmacologic tool and potential lead structure for anticancer therapy.

Abstract
Various 2- and 3-haloallylamines were synthesized and evaluated as inhibitors of the quinone-dependent bovine plasma amine oxidase (BPAO). 3-Haloallylamines, which were previously found to be good inhibitors of the flavin-dependent mitochondrial monoamine oxidase (MAO), exhibited a time-dependent inactivation of BPAO, with the 2-phenyl analogs being more potent than the 2-methyl analogs. No plateau of enzyme activity loss was observed, suggestive of a lack of competitive partitioning to normal turnover. The (E)- and (Z)-2-phenyl-3-fluoro analogs were the most potent (low microM IC(50)s), with the corresponding 3-bromo and 3-chloro analogs being >10-fold less potent. In each case, the Z-isomers were more potent than the E-isomers, the reverse of the configurational inhibitory preference observed with MAO. In contrast to the 2-phenyl analogs, 3-phenyl-2(or 3)-chloroallylamines displayed a partitioning behavior, consistent with these being both substrates and inactivators of BPAO.

Abstract
TPP+ (tetraphenylphosphonium ion) and its analogues were found to act as powerful competitive inhibitors of BSAO (bovine serum amine oxidase). The binding of this new class of inhibitors to BSAO was characterized by kinetic measurements. TPP+ can bind to the BSAO active site by hydrophobic and by coulombian interactions. The binding probably occurs in the region of the 'cation-binding site'[Di Paolo, Scarpa, Corazza, Stevanato and Rigo (2002) Biophys. J. 83, 2231-2239]. Under physiological conditions, the association constant of TPP+ for this site is higher than 10(6) M(-1), the change of enthalpy being the main free-energy term controlling binding. Analysis of the relationships between substrate structure and extent of inhibition by TPP+ reveals some new molecular features of the BSAO active site.

Abstract
1,5-diamino-2-pentyne (DAPY) was found to be a weak substrate of grass pea (Lathyrus sativus, GPAO) and sainfoin (Onobrychis viciifolia, OVAO) amine oxidases. Prolonged incubations, however, resulted in irreversible inhibition of both enzymes. For GPAO and OVAO, rates of inactivation of 0.1-0.3 min(-1) were determined, the apparent KI values (half-maximal inactivation) were of the order of 10(-5) m. DAPY was found to be a mechanism-based inhibitor of the enzymes because the substrate cadaverine significantly prevented irreversible inhibition. The N1-methyl and N5-methyl analogs of DAPY were tested with GPAO and were weaker inactivators (especially the N5-methyl) than DAPY. Prolonged incubations of GPAO or OVAO with DAPY resulted in the appearance of a yellow-brown chromophore (lambda(max) = 310-325 nm depending on the working buffer). Excitation at 310 nm was associated with emitted fluorescence with a maximum at 445 nm, suggestive of extended conjugation. After dialysis, the color intensity was substantially decreased, indicating the formation of a low molecular mass secondary product of turnover. The compound provided positive reactions with ninhydrin, 2-aminobenzaldehyde and Kovacs' reagents, suggesting the presence of an amino group and a nitrogen-containing heterocyclic structure. The secondary product was separated chromatographically and was found not to irreversibly inhibit GPAO. MS indicated an exact molecular mass (177.14 Da) and molecular formula (C10H15N3). Electrospray ionization- and MALDI-MS/MS analyses yielded fragment mass patterns consistent with the structure of a dihydropyridine derivative of DAPY. Finally, N-(2,3-dihydropyridinyl)-1,5-diamino-2-pentyne was identified by means of 1H- and 13C-NMR experiments. This structure suggests a lysine modification chemistry that could be responsible for the observed inactivation.

Abstract
Bovine plasma amine oxidase (BPAO) was previously shown to be irreversibly inhibited by propargylamine and 2-chloroallylamine. 1,4-Diamine versions of these two compounds are here shown to be highly potent inactivators, with IC50 values near 20 microM. Mono-N-alkylation or N,N-dialkylation greatly lowered the inactivation potency in every case, whereas the mono-N-acyl derivatives were also weaker inhibitors and enzyme activity was recoverable. The finding that the bis-primary amines 1,4-diamino-2-butyne (a known potent inhibitor of diamine oxidases) and Z-2-chloro-1,4-diamino-2-butene are potent inactivators of BPAO is suggestive of unexpected similarities between plasma amine oxidase and the diamine oxidases and implies that it may be unwise to attempt to develop selective inhibitors of diamine oxidase using a diamine construct.
