The SA-152 inactivated thrombin was dialyzed and incubated with 0.5M and 2.5M NaCl and 10 mM TAME. There was no reconstitution of activity of the SA-152 modified thrombin after dialysis and treatment with high concns. of NaCl and TAME. Heparin interactions with the anion-binding site of the high mol. wt. recognition center in the thrombin mol. did not significantly influence the values of the kinetic consts. for the enzyme inhibition by SA-152. This finding is consistent with the hypothesis on the irreversible binding of SA-152 in the active center of the enzyme.

On the basis of QSAR models anal. it was concluded that hydrophobic interactions play an essential role in APh-AChE binding, whereas for APh-BuChE binding steric interactions are essential. Presence of at least two APh binding centers on the surface of AChE and BuChE is suggested.

    Individual components of the GABA-A receptor are capable of mutual allosteric interactions. Allosteric interactions between the specific binding sites in the GABA-dependent receptor-channel complex were investigated in rat brain synaptosome and membrane prepns. Paired competitive comparisons for bicyclic phosphorus esters (PBE), picrotoxin, and [3H]GABA were performed. The effects of BPE and picrotoxin on the GABA-dependent permeability for 36Cl- in vitro were also examd. With the combined use of picrotoxin and 4-Me, 4-Et, and 4-Pr derivs. of BPE, the inhibitory effects of picrotoxin in [3H]GABA binding were diminished. Differences in the effect of BPE and picrotoxin on the transport of 36Cl- into synaptoneurosomes were also found. The results are discussed in terms of possible allosteric interactions between the binding sites for BPE, picrotoxin, and [3H]GABA.

    The vibrational spectra were studied of hexafluoroacetonimine [(CF3)2CNH]. By using isotope substitution (H/D), the earlier calcd vibrational attributes were more precisely defined. The vibrational spectra of (CF3)2CNH are described by the C5-symmetry model. The inverse vibrational problem was solved in an approxn. of the valence-force field. The IR spectra of gaseous and solid samples and the Raman spectra of all the aggregate states were studied. The IR spectra were recorded on a Fourier spectrometer with a resoln. of 0.5 cm-1 in the 100-4000 cm-1 range. The IR spectra with high resoln. (0.1 cm-1) were recorded at 30-350 cm-1 using a Ge bolometer cooled with liq. He. The Raman spectra were obtained with a resoln. of 3 cm-1 (50-4000 cm-1). The obtained valence-force field can be used for anal. of the vibrational spectra of other N-substituted hexafluoroacetonimines.

    5,5-Bis(hydroxymethyl)-2-oxo-[1-(2-trifluoromethyl)-3,3,3- trifluoropropionamido)-1-trifluoromethyl-2,2,2-trifluoroethyl- 1,3,2-dioxaphosphan (CA-423) is an in vitro inhibitor of the Escherichia coli uridine and thymidine phosphorylases. Unlike widely studied nucleoside analogues, this compound binds to the enzymes irreversibly. Its LD50 in mice was 40 mg/kg. Due to the involvement of pyrimidine phosphorylases in carcinogenesis and the relatively low toxicity of CA-423, it is promising for anticancer therapy.

  146. Inhibition of enzymatic activity of alpha-thrombin by low molecular weight synthetic inhibitor
    By Kireeva E G; Strukova S M; Dugina T N; Sokolov V B; Aksinenko A Iu From Biokhimii a (Moscow, Russia) (1992), 57(1), 21-6. Language: Russian, Database: MEDLINE
    The effect of the organophosphoric inhibitor, SA-152, on the fibrinogen-coagulating and TAME-esterase activity of bovine alpha-thrombin was studied. The irreversible inhibition constants (k11 = 1.1 x 10(4) M-1.min-1,Ki = 0.7 x 10(-4) M, k2 = 0.8 min-1 towards the coagulating activity and kII = 0.7 x 10(4) M-1.min-1, Ki = 0.3 x 10(-4) M, k2 = 0.2 min-1 towards the esterase activity) were determined. The SA-152 inactivated alpha-thrombin was dialyzed and incubated with 0.5 M and 2.5 M NaCl and 10 mM TAME. There was no reconstitution of activity of the SA-152 modified alpha-thrombin after dialysis and treatment with high concentrations of NaCl and TAME. Heparin interactions with the anion-binding site of the high molecular weight recognition center in the alpha-thrombin molecule did not significantly influence the values of the kinetic constants for the enzyme inhibition by SA-152. This finding is consistent with the hypothesis on the irreversible binding of SA-152 in the active center of the enzyme.

  148. Effects of gamma-aminobutyric acid antagonist, 4-ethyl bicyclo-phosphate, on total and synaptic evoked responses in neurons of hippocampal slices
    By Pervukhin G Ia; Sharonova I N; Prokof'ev S E; Fedorov N B; Sokolov V B; Martynov I V From Biulleten' eksperimental'noi biologii i meditsiny (1991), 111(4), 339-41. Language: Russian, Database: MEDLINE
    Influence of 4-E-BPE on the amplitude of population spices (PS) evoked in CA1 area by Shaffer collateral stimulation in hippocampal slices were analysed. Bath application of 4-E-BPE (10(-6)-10(-5) M) led to a pronounced increase in the amplitude of the PS, the appearance of secondary PS and then introduction of GABA led to restoring original state. The 4-E-BPE was more potent than picrotoxin. These findings suggest that 4-E-BPE suppress inhibitory synaptic transmission in the CA1 region of hippocampus.

  149. Inhibition of cholinesterase activity with fluorine-containing derivatives of alpha-aminophosphonic acid
    By Kuusk V V; Morozova I V; Agabekian R S; Aksinenko A Iu; Epishina T A; Sokolov V B; Kovaleva N V; Razdol'skiy A N; Fetisov V N; Martynov I V From Bioorganicheskaia khimiia (1990), 16(11), 1500-8. Language: Russian, Database: MEDLINE
    A series of O,O-diethyl-1-(N-alpha-hydrohexafluoroisobutyryl)aminoalkylphos phonates (APh) has been synthesized and their interaction with human erythrocyte acetylcholinesterase (AChE) and with horse serum butyrylcholinesterase (BuChE) studied. Most of the APhs inactivated the cholinesterases irreversible through formation of the enzyme-inhibitor intermediate. The inactivation rate constants and the enzyme-inhibitor intermediate dissociation constants are calculated. The quantitative structure-activity relationships including both hydrophobic and calculated steric parameters of substituents are developed for APh--ChE interactions. Molecular mechanics (programme MM2) was used for determining steric parameters (Es). On the basis of QSAR models analysis it was concluded that hydrophobic interactions play an essential role in APh--AChE binding, whereas for APh--BuChE binding steric interactions are essential. Presence of at least two APh binding centres on the surface of AChE and BuChE is suggested.

    Influence of O,O,-diethyl-1-(N-alpha-hydrohexafluoroisobutyryl)amino-1- methylpropylphosphonate and O,O-diisobutyl-1-[2-(ethoxycarbonyl)aminoperfluoroprop-2-yl] -1- methylpropylphosphonate on the level of production of human proinsulin secreted by a genetically engineered culture Bacillus subtilis AJ 73 (pBINS1.0.) has been studied. The above phosphonates, being non-toxic for microorganisms, reduced degradation of proinsulin by serine proteinases.

  152. Comparative study of the interaction of acetylcholinesterases of human erythrocytes and the heads of houseflies with phosphorylated alkylchloroformoximes
    By Shataeva G A; Makhaeva G F; Iankovskaia V L; Sokolov V B; Ivanov A N From Zhurnal evoliutsionnoi biokhimii i fiziologii (1988), 24(6), 791-6. Language: Russian, Database: MEDLINE
    Studies have been made on the interaction of four types of phosphorylated alkylchloroformoximes, i.e. analogues of an insecticide-acaricide valexon, with acetylcholinesterases from human erythrocytes and from the heads of the housefly Musca domestica. Antiacetylcholinesterase activity of the drugs depended both on the structure of the organophosphorus compounds, and the origin of the enzyme, indicating the existence of differences in the active surface of these acetylcholinesterases. Incorporation of one or two chloride atoms into alkylchloroformoxime group of the cleaved part of the organophosphorus compounds increased anticholinesterase activity with respect to both enzymes. Diethyl derivatives of these drugs exhibited higher specificity with respect to housefly enzyme as compared to human acetylcholinesterase.

  154. Interaction of dialkyl(alpha-carbomethoxy-beta,beta,beta-trifluoro- ethyl) phosphates with mammalian esterases
    By Makhaeva G F; Fetisov V I; Sokolov V B; Iankovskaia V L; Goreva T V From Bioorganicheskaia khimiia (1987), 13(1), 33-7. Language: Russian, Database: MEDLINE
    The interaction of dialkyl (alpha-carbometoxy-beta,beta,beta-trifluoroethyl) phosphates (RO)2P(O) . OCH(CF3)COOMe (R = Me, Et, Pr, Pri, Bu, Bui, Am, Hex) (I-VIII) with human erythrocyte acetylcholinesterase, horse serum butyrylcholinesterase, pig liver carboxylesterase was studied and acute toxicity in mice was estimated. Compounds (I)-(VIII) were not hydrolyzed by carboxylesterase, slowly and irreversibly inhibited acetylcholinesterase (kII = 10(2)-10(4) M-1 X min-1) and more efficiently inhibited butyrylcholinesterase and carboxylesterase (kII = 10(3)-10(7) M-1 X min-1). The structure--antienzymatic activity relationships were investigated. With increasing of hydrophobicity of alkoxy groups, antienzymatic activity to butyrylcholinesterase and carboxylesterase ("sites of loss") rises equally and more significantly, than antiacetylcholinesterase activity (delta lg kII 1.0 and 2.4 for R = CH3 and C5H11 resp.). Branching at the alpha-position of alkoxy groups leads to sharp reducing of acetylcholinesterase and butyrylcholinesterase inhibition constants, the carboxylesterase inhibition mechanism becoming reversible. Multiple regression analysis (the Kubinyi model) showed that influence of steric hindrances is revealed at the phosphorylation stage. It was found that phosphates (I)-(VIII) possess low acute toxicity in mice (900-2000 mg/kg). The toxicity of this homologous series appears to be independent of the hydrophobicity. Role of esterases in toxicological effect of compounds (I)-(VIII) is discussed.
