Thakur, Alok S. published the artcileSynthesis and Anticonvulsant Effect of Novel Thiazolidinedione Containing Benzene-sulfonylurea and Sulfonylthiourea Derivatives, HPLC of Formula: 3696-23-9, the publication is Central Nervous System Agents in Medicinal Chemistry (2016), 16(2), 152-157, database is CAplus and MEDLINE.

A newer series of 1-(4-substitutedphenyl)-3-(4-((2,4-dioxothiazolidin-5-lidene)methyl)phenyl sulfonyl)urea/thiourea (4a-l) were synthesized for their anticonvulsant activity. The activity is attributed to its potential to restrain astrocytic Na+, 2HCl, and K+ co-transport similar to torasemide which has sulfonylurea in its structure. Torasemide having the similar action as the furosemide that obstructs kainic acid-induced elec. discharges observed from cortex and it has neuroprotective agents, for instance antagonizing the N-methyl-D-aspartate (NMDA) and non-NMDA receptors for evaluating antiepileptic activity. The structures of new derivatives were established by elemental anal. and spectroscopic techniques viz. FTIR, 1H NMR and LC-MS. The all twelve derivatives were assessed for anticonvulsant activity at three different doses at 30, 100 and 300 mg/kg body weight into maximal electroshock (MES) and s.c. pentylenetetrazole (sports) models. Compounds 4c and 4e were formed to be most active among all the derivatives for both the models of anticonvulsant activity. Beside these compounds 4g, 4i and 4k also possessed the prominent anticonvulsant activity devoid of any neurotoxicity. The sulfonylurea and sulfonylthiourea both were proved to be effective anticonvulsant pharmacophore. Other structure activity relationships were established by considering the aspect of substitution in the lead.

Padhya, A. C. published the artcileAntimicrobial properties of azomethines of salicylaldehyde derivatives, Name: 5-Bromo-3-chloro-2-hydroxybenzaldehyde, the publication is Indian Journal of Microbiology (1974), 14(2), 91-3, database is CAplus.

Many azomethine derivatives of 5-chloro-, 5-bromo-, 3-bromo-5-chloro-, and 5-bromo-3-chlorosalicylaldehyde were prepared and tested for their antibacterial and antifungal activities. The azomethine derivatives of 5-chlorosalicylaldehyde showed no antibacterial activity, but were active against all tested fungi except Nocardia asteroides. The azomethine derivatives of 5-bromosalicylaldehyde had no antibacterial activity, and species variable antifungal activity. The azomethine derivatives of 5-bromo-3-chloro- and 3-chloro-5-bromosalicylaldehyde were poor antifungal agents, compared with the 5-chloro or 5-bromosalicylaldehyde derivatives, probably due to the blocking of the phenolic group by substituents on both sides. However, they were better antibacterial agents than the 5-monosubstituted salicylaldehyde derivatives, most being active against S. aureus at 6.25-12.5 μg/ml.

A novel series of 1,2,4-thiadiazole compounds was discovered as selective S1P₁ agonists. The extensive structure-activity relationship studies for these analogs were reported. Among them, I was identified to show high in vitro potency with reasonable free unbound fraction in plasma (F_u > 0.5%), good brain penetration (BBR > 0.5), and desirable pharmacokinetic properties in mouse and rat. Oral administration of 1 mg/kg I resulted in significant peripheral lymphocytes reduction at 4 h after dose and rapid lymphocytes recovery at 24 h. Compound I showed a transient lymphopenia profile in the repeated dose study in mouse. In addition, I also demonstrated efficacy comparable to that of FTY720 (II) in the mouse EAE model of MS.

Cossement, D. published the artcileSelf-assembled monolayers of branched alkylsilanes on polycrystalline titanium surfaces, Name: Dichloro(methyl)(octyl)silane, the publication is Surface and Interface Analysis (2000), 30(1), 56-60, database is CAplus.

The silanization reaction on polycrystalline Ti surfaces was studied from the point of view of engineering a densely packed chemisorbed layer at the interface. For this purpose methyl-n-octyldichlorosilane (MODCS) and 2-methyl-1-trichlorosilylundecane (2MTCSU) were used and compared with n-octyltrichlorosilane (OTCS). XPS and contact angle measurements reveal that 2MTCSU forms well covering but not so densely packed monolayers as does OTCS. In contrast to 2MTCSU, MODCS does not provide a proper modification of the surface because of the small amount of mols. chemisorbed on the surface.

Kinetics of controlled simultaneous copolymerization of hexamethylcyclotrisiloxane (D₃) with functional cyclotrisiloxanes was studied using n-BuLi in THF as initiator. Trifunctional (MeXSiO)₃ (X₃), where X = vinyl, trifluoropropyl or chloropropyl group, and monofunctional monomers [(Me₂SiO)₂MeXSiO] (D₂X), where X = cyanopropyl or n-octyl group, were used as monomers. Reactivity ratios for each pair of comonomers were determined and the possibility of synthesis of gradient copolymers by this method is discussed.

Parry, Geraint published the artcileNovel auxin transport inhibitors phenocopy the auxin influx carrier mutation aux1, Quality Control of 33697-81-3, the publication is Plant Journal (2001), 25(4), 399-406, database is CAplus and MEDLINE.

The hormone auxin is transported in plants through the combined actions of diffusion and specific auxin influx and efflux carriers. In contrast to auxin efflux, for which there are well documented inhibitors, understanding the developmental roles of carrier-mediated auxin influx has been hampered by the absence of specific competitive inhibitors. However, several mols. that inhibit auxin influx in cultured cells have been described recently. The physiol. effects of two of these novel influx carrier inhibitors, 1-naphthoxyacetic acid (1-NOA) and 3-chloro-4-hydroxyphenylacetic acid (CHPAA), have been investigated in intact seedlings and tissue segments using classical and new auxin transport bioassays. Both mols. do disrupt root gravitropism, which is a developmental process requiring rapid auxin redistribution. Furthermore, the auxin-insensitive and agravitropic root-growth characteristics of aux1 plants were phenocopied by 1-NOA and CHPAA. Similarly, the agravitropic phenotype of inhibitor-treated seedlings was rescued by the auxin 1-naphthaleneacetic acid, but not by 2,4-dichlorophenoxyacetic acid, again resembling the relative abilities of these two auxins to rescue the phenotype of aux1. Further investigations have shown that none of these compounds block polar auxin transport, and that CHPAA exhibits some auxin-like activity at high concentrations While results indicate that 1-NOA and CHPAA represent useful tools for physiol. studies addressing the role of auxin influx in planta, 1-NOA is likely to prove the more useful of the two compounds

Synthesis and ¹H NMR spectra in D₂O of 4 betaines and 19 betaine complexes with mineral acids containing 2 or 3 CH₂ groups in the tether, N⁺-(CH₂)_n-COO^–, n=2,3, and diverse volume of the pos. charged groups are reported. In compounds containing three CH₂ groups in the tether and three substituents at the nitrogen atom or α, α’-disubstituted pyridine ring, a characteristic multiplet for an AA’MM’X₂ spin system is observed This is consistent with preference for trans conformation (68-85%). In the spectra of compounds with two CH₂ groups in the tether or three CH₂ groups and unsubstituted pyridine ring, the multiplet changes to a triplet and gives apparent A₂X₂ and A₂M₂X₂ spectra, resp., consistent with no significant conformational preference. Both the number of CH₂ groups in tether and the bulkiness of the charged groups are responsible for the observed differences of N⁺CH₂ multiplicity and reflect changes in conformational preferences. According to the PM3 calculations, in the gas phase a gauche-like conformer is more stable than the trans, but in aqueous solution it is reverse.
