A fast and efficient microwave-assisted solid phase peptide synthesis (MW-SPPS) of a 51mer peptide, the main heparin-binding site (60-110) of human pleiotrophin (hPTN), using 2-chlorotrityl chloride resin (CLTR-Cl) following the 9-fluorenylmethyloxycarbonyl/tert-Bu (Fmoc/tBu) methodol. and with the standard N,N’-diisopropylcarbodiimide/1-hydroxybenzotriazole (DIC/HOBt) coupling reagents, is described. An MW-SPPS protocol was for the first time successfully applied to the acid labile CLTR-Cl for the faster synthesis of long peptides (51mer peptide) and with an enhanced purity in comparison to conventional SPPS protocols. The synthesis of such long peptides is not trivial and it is generally achieved by recombinant techniques. The desired linear peptide was obtained in only 30 h of total processing time and in 51% crude yield, in which 60% was the purified product obtained with 99.4% purity. The synthesized peptide was purified by reversed phase high performance liquid chromatog. (RP-HPLC) and identified by electrospray ionization mass spectrometry (ESI-MS). Then, the regioselective formation of the two disulfide bridges of hPTN 60-110 was successfully achieved by a two-step procedure, involving an oxidative folding step in dimethylsulfoxide (DMSO) to form the Cys⁷⁷-Cys¹⁰⁹ bond, followed by iodine oxidation to form the Cys⁶⁷-Cys⁹⁹ bond.

McRae Page, Samantha published the artcilePromoting cell adhesion on slippery phosphorylcholine hydrogel surfaces, Category: chlorides-buliding-blocks, the publication is Journal of Materials Chemistry B: Materials for Biology and Medicine (2014), 2(6), 620-624, database is CAplus and MEDLINE.

The growing interest in regenerative medicine has created a need for superior polymer matrixes that suit multiple phys., mech., and biol. requirements. While the phospholipid bilayer of a cell membrane is considered optimal for interacting with biologics, polymeric materials composed of 2-methacryloyloxyethyl phosphorylcholine (MPC) offer a cell membrane-like synthetic alternative. In this work, thiol-containing phosphorylcholine polymers were synthesized by radical copolymerization of a lipoic acid-functionalized methacrylate with MPC. The canonical cell adhesion oligopeptide (GRGDS) was incorporated into the polymers by copolymerization of a GRGDS-containing methacrylamide prepared by solid phase peptide synthesis. The relative amounts of phosphorylcholine, lipoic acid and oligopeptide were controlled by the monomer feed ratios, and the polymers were characterized by NMR spectroscopy and aqueous gel permeation chromatog. (GPC). These multifunctional polymers formed hydrogels rapidly (<10 min) by Michael addition when poly(ethylene glycol)diacrylate (PEGDA) was added at pH 9 – an initiator-free gelation performed in a completely aqueous environment. Two cell lines, live mouse skeletal muscle myoblasts (C₂C₁₂) and human ovarian cancer (SKOV3) cells, were observed to specifically attach, spread and proliferate only on hydrogels containing the GRGDS peptide sequence, with a notable dependence on peptide concentration The remarkable hydrophilicity and biocompatibility attributed to polyMPC combined with the facile gelation conditions of these polymers affords a platform of new bio-cooperative materials suitable for cell studies.

Benzofuroquinolinediones (7c and 7d) were synthesized by base-catalyzed condensation of dichloroquinolinediones with phenolic derivatives Their dialkylaminoalkoxy derivatives (8i-8p) were prepared by reaction with various dialkylaminoalkyl chlorides. The cytotoxicity of the synthesized compounds was evaluated against eight types of human cancer cell lines, and their topoisomerase II inhibition was assessed. In general, the cytotoxicity of benzofuroquinolinediones (8i-8p) was similar or superior to that of doxorubicin and showed more potent inhibitory activity than naphthofurandiones (8a-8h). Also, most of the compounds exhibited excellent topoisomerase II inhibitory activity at a concentration of 5 μM and two compounds, 8d and 8i, showed IC₅₀ values of 1.19 and 0.68 μM, resp., and were much more potent than etoposide (IC₅₀ = 78.4 μM), but similar to doxorubicin (IC₅₀ = 2.67 μM). However their inhibitory activity on topoisomerase I was lower, and 8d and 8i showed IC₅₀ values of 42.0 and 64.3 μM, resp.

To explore the effect of substituents on Ph motif on sulfonyl function of novel anticancer 4-phenyl-1-benzenesulfonylimidazolidinones, electron donating or withdrawing substituents were introduced at 3 or 4-position and the analogs were tested against human lung (A549) and colon (HCT-15) cancer cell lines. Quant. structure activity relation of the 4-substituted series shows that only STERIMOL L values are well correlated. The increment of substituent’s volume enhances the activity against both cell lines. The small substituent at 3-position addnl. increases the activity. However naphthyl group in place of Ph reduces the activity. Therefore the Ph motif with sterically large substituent at 4-position and small substituent at 3-position may be important for their activity. Integration of these substituents’ effects into the structural design led to discover the more potent analog, 4-phenyl-1-(N-acetylindoline-5-sulfonyl)imidazolidinone.

Kim, Seon Hwa published the artcileDegradation of prochloraz by rice bakanae disease pathogen Fusarium fujikuroi with differing sensitivity: a possible explanation for resistance mechanism, Safety of N-(2-(2,4,6-Trichlorophenoxy)ethyl)propan-1-amine, the publication is Journal of the Korean Society for Applied Biological Chemistry (2010), 53(4), 433-439, database is CAplus.

The fungicide prochloraz was subjected to degradation by the pathogen causing rice Bakanae disease, Fusarium fujikuroi, in order to gain an insight into the mechanisms of sensitivity and resistance to the fungicide. Growth-inhibiting assays of pathogens were conducted on potato dextrose agar (PDA) plates by a paper-disk agar-diffusion method. Significant growth inhibition of the sensitive strain CF106 was observed at the recommended treatment level of prochloraz, whereas negligible growth inhibition of the resistant strain CF245 was observed at the same treatment level. The strain CF245 was shown to be able to grow on PDA with 500 mg/L of the fungicide, which is significantly higher than its recommended treatment level. Growth-inhibiting assays of pathogens were also conducted in potato dextrose broth (PDB) medium supplemented with prochloraz at different concentrations, measuring their biomass weights over the incubation period. Significant growth inhibition was observed in the strain CF106 at a level of 0.5 mg/L, but negligible growth inhibition was observed in the strain CF245 at the same treatment level with the strain CF106. The strain CF245 could grow in PDB supplemented with 1.0 mg/L of prochloraz. The degradation of prochloraz by the 2 strains was evaluated by gas liquid chromatog. and mass spectrometry analyses. The strain CF245 completely degraded 1.0 mg/L prochloraz in 5 days after incubation, whereas no degradation of prochloraz was observed by the strain CF106 at the same treatment level. Liquid chromatog. Q-TOF MS detected N-(2-(2,4,6-trichlorophenoxy)ethyl)propan-1-amine as a major degradation product of prochloraz by the strain CF245. These results indicated that the degradation of prochloraz may account for the reduced sensitivity of the strain CF245 to prochloraz.

Nineteen novel N-(2-pyrrolidinylmethyl)benzamides I (R = OMe, OEt, OCHMe₂, or Cl; R¹ and R² = H, Br, or Cl; R³ and R⁴ = H or Et) were synthesized and tested for dopamine receptor blockade in vivo by their ability to block the apomorphine syndrome in the rat. Several compounds were more potent than sulpiride as dopamine receptor blockers and displayed low liability to induce extrapyramidal side effects (catalepsy) in the rat. The blockade of dopamine receptor activity in vivo was mainly confined to the levorotatory isomers having the S absolute configuration. Structure-activity relationships are discussed.

Wakatake, Takanori published the artcileAn auxin transport network underlies xylem bridge formation between the hemi-parasitic plant Phtheirospermum japonicum and host Arabidopsis, Product Details of C8H7ClO3, the publication is Development (Cambridge, United Kingdom) (2020), 147(14), dev187781, database is CAplus and MEDLINE.

Parasitic plants form vascular connections with host plants for efficient material transport. The haustorium is the responsible organ for host invasion and subsequent vascular connection. After invasion of host tissues, vascular meristem-like cells emerge in the central region of the haustorium, differentiate into tracheary elements and establish a connection, known as a xylem bridge, between parasite and host xylem systems. Despite the importance of this parasitic connection, the regulatory mechanisms of xylem bridge formation are unknown. Here, we show the role of auxin and auxin transporters during the process of xylem bridge formation using an Orobanchaceae hemiparasitic plant, Phtheirospermum japonicum. The auxin response marker DR5 has a similar expression pattern to tracheary element differentiation genes in haustoria. Auxin transport inhibitors alter tracheary element differentiation in haustoria, but biosynthesis inhibitors do not, demonstrating the importance of auxin transport during xylem bridge formation. The expression patterns and subcellular localization of PIN family auxin efflux carriers and AUX1/LAX influx carriers correlate with DR5 expression patterns. The cooperative action of auxin transporters is therefore responsible for controlling xylem vessel connections between parasite and host.
