Cooperative hierarchical self-assembly of peptide dendrimers and linear polypeptides into nanoarchitectures mimicking viral capsids

Peptidesomes are nanoparticles that are built by a two-step self-assembly of globular peptide dendrimers with lysine endgroups (red spheres in picture) and poly(L-leucine) carrying one glutamic acid residue (blue lines with red dot). These viral-capsid-mimicking nanoarchitectures exhibit high gene transfection efficacy and thus are promising nonviral vectors for biomedical applications. Copyright

E-factor minimized protocols for the polystyryl-BEMP catalyzed conjugate additions of various nucleophiles to alpha,beta-unsaturated carbonyl compounds

Efficient protocols for the addition of carbon-, sulphur- and nitrogen-nucleophiles to alpha,beta-unsaturated carbonyl compounds catalyzed by PS-BEMP have been reported. The adoption of solvent-free conditions (SolFC) was crucial for improving the efficiency of all the processes, while by using an organic reaction medium poor results were obtained. Addition reactions were performed by using equimolar amounts of reagents, and the products were isolated by simple filtration with the minimal amount of organic solvent. This approach allowed the E-factor, a measure of the waste of a reaction, to be minimized. Further waste minimization (95.7% compared to batch protocol) has been accomplished by defining a larger scale continuous-flow protocol operating under SolFC.

Synthetic stitching with silicon: Geminal alkylation-hydroxylation of alkynyl carbonyl compounds

A new strategy for the synthesis of beta-carbonyl-substituted tertiary alcohols from alpha,beta-alkynyl ketones and esters has been demonstrated. A silicon tether is used to internally deliver an alkyl group, which, combined with a C-Si to C-O transformation, can regio- and diastereoselectively “stitch” together geminal C-C and C-O bonds at the beta-position of an electron-withdrawing group. Regioselective alkyne hydrosilylation by a trans addition process provides clean access to trisubstituted vinylsilanes. Subsequent one-pot fluoride-induced C-C bond formation and oxidation of the resulting tertiary silane, a type of silane not normally reactive to such conditions, affords the desired products. The utility of neighboring ketone and carboxylate groups in promoting the oxidation of these highly hindered tertiary alcohols, an observation that may affect synthetic design of routes depending on such oxidations, is demonstrated. Good diastereoselection (>10:1) is observed for substrates bearing gamma-alkoxy stereocenters. Copyright

METHOD OF PRODUCING OPTICALLY ACTIVE ALCOHOL

This invention relates to a process for producing optically active alcohols using asymmetric reduction of aromatic ketones. This process gives optically active alcohols in high enantioselectivity at large scale production. Aromatic ketones represented by formula (I) [wherein, R1 are selected from hydrogen atom, halogen atom, lower alkyl group etc. R2 is -(CH2)n-R3 [wherein, n is 1 to 5 integer. R3 are selected from hydrogen atom, halogen atom, lower alkoxycarbonyl group etc. and formula (II) and (III). {wherein, R4 is selected from lower alkyl group (1 to 5 carbon atom) etc. R5 and R6 are the same or different and are selected from hydrogen atom, halogen atom, lower alkyl group etc.}]] are reduced by sodium borohydride, chlorotrimethylsilane and optically active 2-[bis(4-methoxyphenyl)hydroxymethyl]pyrrolidine represented by formula (IV) to give optically active alcohol represented by formula (V) stereoselectively. (wherein, R1 and R2 are as defined above.)

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C20H20FNO4, you can also check out more blogs about189028-95-3

Design, synthesis, and biological activity of isophthalic acid derivatives targeted to the C1 domain of protein kinase C

Protein kinase C (PKC) is a widely studied molecular target for the treatment of cancer and other diseases. We have approached the issue of modifying PKC function by targeting the C1 domain in the regulatory region of the enzyme. Using the X-ray crystal structure of the PKC delta C1b domain, we have discovered conveniently synthesizable derivatives of dialkyl 5-(hydroxymethyl)isophthalate that can act as potential C1 domain ligands. Structure-activity studies confirmed that the important functional groups predicted by modeling were indispensable for binding to the C1 domain and that the modifications of these groups diminished binding. The most promising compounds were able to displace radiolabeled phorbol ester ([3H]PDBu) from PKC alpha and delta at Ki values in the range of 200-900 nM. Furthermore, the active isophthalate derivatives could modify PKC activation in living cells either by inducing PKC-dependent ERK phosphorylation or by inhibiting phorbol-induced ERK phosphorylation. In conclusion, we report here, for the first time, that derivatives of isophthalic acid represent an attractive novel group of C1 domain ligands that can be used as research tools or further modified for potential drug development.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 102029-44-7, help many people in the next few years.SDS of cas: 102029-44-7
