Bachtiger, Fabienne;Congdon, Thomas R.;Stubbs, Christopher;Gibson, Matthew I.;Sosso, Gabriele C. research published 《 The atomistic details of the ice recrystallisation inhibition activity of PVA》, the research content is summarized as follows. Understanding the ice recrystallization inhibition (IRI) activity of antifreeze biomimetics is crucial to the development of the next generation of cryoprotectants. In this work, we bring together mol. dynamics simulations and quant. exptl. measurements to unravel the microscopic origins of the IRI activity of poly(vinyl)alc. (PVA)-the most potent of biomimetic IRI agents. Contrary to the emerging consensus, we find that PVA does not require a “lattice matching” to ice in order to display IRI activity: instead, it is the effective volume of PVA and its contact area with the ice surface which dictates its IRI strength. We also find that entropic contributions may play a role in the ice-PVA interaction and we demonstrate that small block co-polymers (up to now thought to be IRI-inactive) might display significant IRI potential. This work clarifies the atomistic details of the IRI activity of PVA and provides novel guidelines for the rational design of cryoprotectants.

Current research based on the development of promising anticancer chemotherapeutics is a great challenge to scientists to combat the pervasiveness of pernicious cancer. In line with this, the aim of this work is to develop a set of 9-arylacenaphtho[1,2-b]quinoxaline analogs with the capability of imaging, as well as terminating, cancer cells in the human body, exploiting the powerful anticancer activity of the quinoxaline and acenaphthene moieties.

Srinivasa research published 《 Design, Synthesis, and Structural Analysis of Cladosporin-Based Inhibitors of Malaria Parasites》, the research content is summarized as follows. Here we have described a systematic structure activity relationship (SAR) of a set of compounds inspired from cladosporin, a tool compound that targets parasite (Plasmodium falciparum) lysyl tRNA synthetase (KRS). Four sets of analogs, synthesized based on point changes in the chem. scaffold of cladosporin and other logical modifications and hybridizations, were assessed using high throughput enzymic and parasitic assays along with in vitro pharmacokinetics. Co-crystallization of the most potent compound in our series (CL-2) with PfKRS revealed its structural basis of enzymic binding and potency. Further, we report that CL-2 has performed better than cladosporin in terms of metabolic stability. It thus represents a new lead for further optimization toward the development of antimalarial drugs. Collectively, along with a lead compound, the series offers insights on how even the slightest chem. modification might play an important role in enhancing or decreasing the potency of a chem. scaffold.

A variety of dihydroquinazolin-4(1H)-one derivatives (1-37) were synthesized via “one-pot” three-component reaction scheme by treating aniline and different aromatic aldehydes with isatoic anhydride in the presence of acetic acid. Chem. structures of compounds were deduced by different spectroscopic techniques including EI-MS, HREI-MS, 1H-, and 13C-NMR. Compounds were subjected to α-amylase and α-glucosidase inhibitory activities. A number of derivatives exhibited significant to moderate inhibition potential against α-amylase (IC₅₀ = 23.33 ± 0.02-88.65 ± 0.23 μM) and α -glucosidase (IC₅₀ = 25.01 ± 0.12-89.99 ± 0.09 μM) enzymes, resp.

Structure-activity relationship (SAR) was rationalized by analyzing the substituents effects on inhibitory potential. Kinetic studies were implemented to find the mode of inhibition by compounds which revealed competitive inhibition for α-amylase and non-competitive inhibition for α-glucosidase. However, in silico study identified several important binding interactions of ligands (synthetic analogs) with the active site of both enzymes.

Azeri, Oezge;Schoenfeld, Dennis;Noirez, Laurence;Gradzielski, Michael research published 《 Structural control in micelles of alkyl acrylate-acrylate copolymers via alkyl chain length and block length》, the research content is summarized as follows. Amphiphilic copolymers with poly (alkyl acrylate) as hydrophobic and poly (acrylic acid) (AA) as hydrophilic block have been synthesized. The alkyl chain was varied from Bu to dodecyl, thereby varying systematically the polarity of the hydrophobic block whose length was between 35 and 70, while the PAA block had ∼ 100 units. Such relatively short amphiphiles should equilibrate quickly in aqueous solution, and their corresponding self-assembly properties were characterized by means of critical micelle concentration (cmc) determination Detailed information regarding the aggregate structures was obtained by static light scattering (SLS) and small angle neutron scattering (SANS). This could be correlated with the mol. architecture of the copolymers and the degree of ionization of the PAA block. Generally, it is found that the aggregation numbers become smaller upon fully charging the PAA head group and only for dodecyl acrylate really well-defined micellar aggregates are formed. This means that the extent of hydrophobicity of the alkyl acrylate block and its length determine in a clear fashion the propensity for micelle formation and the mass and aggregation number of the formed micelles.
