Syntheses of Furo[3,2-e][1,2,4]triazolo[1,5-c]pyrimidines and Furo[2`,3`: 5,6]-pyrimido[3,4-b][2,3-e]indolo[1,2,4]triazine as a New Ring System

Molecules, 2000
2-Amino-4,5-di-(2-furyl)furan-3-carbonitrile (1) reacted with triethyl orthoacetate to afford the corresponding 2-ethoxyimine derivative (2). The latter compound reacted with phenyl hydrazine, p-fluorobenzylamine and sodium hydrogen sulfide, respectively,

Design, Dimerization, and Recombinant Production of MCh-AMP1–Derived Peptide in Escherichia coli and Evaluation of Its Antifungal Activity and Cytotoxicity

Frontiers in Fungal Biology, 2021
Fungal species resistant to current antifungal agents are considered as a serious threat to human health, the dilemma that has dragged attentions toward other sources of antifungals such as antimicrobial peptides (AMPs).

Fragments of Locusta migratoria apoLp-III provide insight into lipid binding

BBA Advances, 2021
Apolipophorin III (apoLp-III) from Locusta migratoria is an exchangeable apolipoprotein with a critical role in lipid transport in insects. The protein is composed of a bundle of five amphipathic α-helices which undergo a large conformational change upon

Chemical Methods for Peptide and Protein Backbone Cleavage

ChemistryEurope, EarlyView.
Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).

Synthesis and Characterization of Periodic Polypeptides Containing Repeating —(AlaGly)_xGluGly— Sequences [PDF]

, 1992
We have expressed in E. coli a series of periodic polypeptides represented by sequence 1. Our objective has been an understanding of the role of chemical sequence in determining the chain folding behavior of periodic macromolecules.

A personal 360° view of applications of ‘biomimetic’ molecular recognition

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Amino acid sequence of rabbit apolipoprotein E.

Journal of Lipid Research, 1991
The complete amino acid sequence of rabbit apolipoprotein E (apoE) was determined by generating three sets of peptides using cyanogen bromide, endoproteinase AspN, and Staphylococcus aureus V8 protease to cleave the protein.
