Among simple oxidizing agents, only H₂O₂ at concentrations higher than 2% produced a plateau in toad single myelinated nerve fibers in the temporal course of action current. Its effect was mainly due to hypertonicity, but its oxidizing potency was somewhat favorable to plateau formation. p-Quinone depolarized the Ranvier’s node and delayed the repolarization phase at the same time. Although recovery with the addition of cysteine was not so good, its effect was essentially attributable to its oxidizing potency, for hydroquinone at high concentrations caused deterioration. In the plasma membrane of the Ranvier’s node, the repolarization phase of action potential can be delayed most effectively by the –S–M–S– linkage (M represents bivalent transition metals).

The Higuchi plot has been used to evaluate the Kassocn., ΔH, and ΔS values for the 1:1 association between CHCl3 and 6 phosphoryl compounds ΔH forms a linear relation with the change in NMR chem. shift, Δδx, and with ir frequency shift, ΔvC-D measured with CDCl3. Also a linear relation exists between Taft σ* constant and ΔH. On replacing CCl4 with cyclohexane as solvent, the Kassocn. and ΔH values are increased considerably.

Imhoff, Viviane published the artcileInhibitors of the carrier-mediated influx of auxin in suspension-cultured tobacco cells, Quality Control of 33697-81-3, the publication is Planta (2000), 210(4), 580-588, database is CAplus and MEDLINE.

Active auxin transport in plant cells is catalyzed by two carriers working in opposite directions at the plasma membrane, the influx and efflux carriers. A role for the efflux carrier in polar auxin transport (PAT) in plants has been shown from studies using phytotropins. Phytotropins have been invaluable in demonstrating that PAT is essential to ensure polarized and coordinated growth and to provide plants with the capacity to respond to environmental stimuli. However, the function of the influx carrier at the whole-plant level is unknown. New auxin-transport inhibitors which could be employed to investigate its function were identified. Thirty-five aryl and aryloxyalkylcarboxylic acids were assayed for their ability to perturb the accumulation of 2,4-D and 1-NAA in suspension-cultured tobacco (Nicotiana tabacum L.) cells. As 2,4-D and 1-NAA are preferentially transported by the influx and efflux carriers, resp., accumulation experiments utilizing synthetic auxins provide independent information on the activities of both carriers. The majority (60%) of compounds half-inhibited the carrier-mediated influx of [¹⁴C]2,4-D at concentrations of less than 10 μM. Most failed to interfere with [³H]NAA efflux, at least in the short term. Even though they increasingly perturbed auxin efflux when given a prolonged treatment, several compounds were much better at discriminating between influx and efflux carrier activities than naphthalene-2-acetic acid which is commonly employed to investigate influx-carrier properties. Structure-activity relationships and factors influencing ligand specificity with regard to auxin carriers are discussed.

The polysiloxane backbone of the gas chromatog. phase Chirasil-Val has been modified by replacing one Me group per dialkylsiloxy unit by pentyl and hexyl groups, resp. The new phases offer the advantage of reduced polarities and softening points, while the separation factors (α) of enantiomeric pairs of N,O-trifluoroacetyl amino acid Pr esters show small but intriguing deviations from those determined on Chirasil-Val.

Di-Et trichloromethylphosphonate, treated with BuLi followed by an aldehyde (or cycloalkenone), was converted to α-chlorovinylphosphonates, e.g. 85% (Z)-PhCH:C(Cl)(PO₃Et₂), via the intermediate formation of a bisphosphonate and a Wadsworth-Emmons olefination. High (Z) stereoselectivity of the reaction is discussed in terms of the conformational preferences of the adducts.

Suslov, Evgenii V. published the artcileNew chemical agents based on adamantane-monoterpene conjugates against orthopoxvirus infections, Computed Properties of 21286-54-4, the publication is RSC Medicinal Chemistry (2020), 11(10), 1185-1195, database is CAplus and MEDLINE.

Currently, the spectrum of agents against orthopoxviruses, in particular smallpox, is very narrow. Despite the fact that smallpox is well controlled, there is, for many reasons, a real threat of epidemics associated with this or a similar virus. In order to search for new low mol. weight orthopoxvirus inhibitors, a series of amides combining adamantane and monoterpene moieties were synthesized using 1- and 2-adamantanecarboxylic acids as well as myrtenic, citronellic and camphorsulfonic acids as acid components. The produced compounds exhibited high activity against the vaccinia virus (an enveloped virus belonging to the poxvirus family), which was combined with low cytotoxicity. Some compounds had a selectivity index higher than that of the reference drug cidofovir; the highest SI = 1123 was exhibited by 1-adamantanecarboxylic acid amide containing the (-)-10-amino-2-pinene moiety. The produced compounds demonstrated inhibitory activity against other orthopoxviruses: cowpox virus (SI = 30-406) and ectromelia virus (mousepox virus, SI = 39-707).

Bakkas, S. published the artcileDifference in behavior of the reactive electrophiles diethyl trichloromethylphosphonate and carbon tetrachloride towards triethyl phosphite, Related Products of chlorides-buliding-blocks, the publication is Phosphorus, Sulfur and Silicon and the Related Elements (2000), 211-224, database is CAplus.

The reaction of tri-Et phosphite with di-Et trichloromethylphosphonate 2b in the absence of solvents and catalysts yields mainly di-Et (1,1-dichloropropyl)phosphonate and di-Et dichloromethylphosphonate. These main products are accompanied by a variety of byproducts which differ considerably from those obtained in the reaction between tri-Et phosphite and CCl₄. Both reactions would begin by a halophilic substitution of tri-Et phosphite on the pos. halogen. For di-Et trichloromethylphosphonate the formed carbanion would then attack preferentially the C β to P⁺ and the H γ to P⁺ on heterophosphonium cation. In contrast, the less sterically hindered trichloromethyl carbanion formed by the halophilic attack of tri-Et phosphite on CCl₄ would rather attack mainly the pos. P⁺ of this cation. The tetra-Et (dichloromethylene)bisphosphonate previously reported by V. P. Kukhar and E. I. Sagina (1979) to be the main product formed in the thermal reaction between tri-Et phosphite and di-Et trichloromethylphosphonate was not found under the authors’ conditions. Its formation only under photochem. irradiation were observed

Gokanapalli, Anusha published the artcileBenzimidazole bearing Pd-PEPPSI complexes catalyzed direct C2-arylation/heteroarylation of N-substituted benzimidazoles, SDS of cas: 620-20-2, the publication is Applied Organometallic Chemistry (2020), 34(10), e5869, database is CAplus.

A convenient and highly efficient palladium-catalyzed direct C2-arylation/heteroarylation of N-substituted benzimidazole derivatives such as N-benzyl/3-chlorobenzyl/2,4,6-trimethylbenzyl/2,4,6-triisopropylbenzyl/aryl benzimidazoles I (R = H; R¹ = Bn, 4-chlorophenyl, (2,4,6-trimethylphenyl)methyl, etc.) with various aryl/heteroaryl bromides R²Br (R² = Ph, thiophen-3-yl, phenanthren-9-yl, etc.) in the presence of Pd-PEPPSI (palladium-pyridine enhanced pre-catalyst preparation stabilization and initiation) complexes is reported. A series of different sym. and unsym. N,N’-diaralkyl benzimidazole-bearing Pd-PEPPSI complexes II (R = 5-Me, 5,6-dimethyl; R³ = Me, 4-fluorophenyl, (2,4,6-trimethylphenyl)methyl, etc.) was prepared Among all of the prepared complexes, II = (R = 5,6-di-Me, R¹ = R³ = [2,4,6-tris(propan-2-yl)phenyl]methyl) effectively tuned the reaction at a relatively higher rate under mild reaction conditions in an ethanol-water system. In addition, the catalytic process avoids the use of external ligand and additives. Further the reactivity was compared with com. available copper-N-heterocyclic carbene catalyst, but the reaction was less successful. With the optimized reaction conditions, a wide range of 2-aryl/heteroaryl-N-substituted benzimidazoles were synthesized in good to excellent yields via Csp²-H/Csp²-X biaryl cross-coupling.
