Special Issue Information

Dear Colleagues,

This Special Issue is the continuation of our previous special issue "Computational Studies of Structure-Dynamics-Function Relationships in Biomolecules".

Computational Chemistry Methods are nowadays widely applied for studying biomolecular structure, mechanisms, dynamics, and function. Molecular Dynamic (MD) simulations methods, Quantum Mechanic (QM) methods, Combined Quantum Mechanics/Molecular Mechanics (QM/MM), Molecular Docking and other computational techniques have proven to be very useful for fundamental understanding of structure–function relationships in biomolecules, but also very useful for application in drug design, chemical biology and biotechnology. Importantly, the increased computational power and the development of high-performance computing made further possible the growth in synergistic computational–experimental studies in the most actual areas of biomolecular sciences in timeliness manner.  

The current Special Issue aims to attract high quality contributions of modeling biomolecular structure, dynamics, function and interactions with potential of interpretation of experimental data and application in drug design and protein design.

Topics of interest:

  • Development and validation of new Computational Modeling Methods
  • Computational Studies of proteins structure-function relationships
  • Computational investigations of nucleic acids structure–function relationships
  • Modelling of protein and nucleic acids dynamics
  • Protein Docking
  • Protein-ligand interactions
  • Nucleic acid ligand interactions
  • Protein design
  • Computational enzymology–enzymatic reaction mechanisms
  • Proteins homology modeling

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
To explore a new set of anticancer agents, a novel series of pyrazolo[4,3-e]pyrido[1,2-a]pyrimidine derivativeshave been designed and synthesized viacyclocondensation reactions of pyrazolo-enaminone with a series of arylidenemalononitriles; compound 5 was obtained from 5-amino-4-cyanopyrazole. The structures of the target compounds [...] Read more.
To explore a new set of anticancer agents, a novel series of pyrazolo[4,3-e]pyrido[1,2-a]pyrimidine derivativeshave been designed and synthesized viacyclocondensation reactions of pyrazolo-enaminone with a series of arylidenemalononitriles; compound 5 was obtained from 5-amino-4-cyanopyrazole. The structures of the target compounds were investigated by spectral techniques and elemental analysis (IR, UV–Vis, 1H NMR, 13C NMR and ESI-MS). All compounds were evaluated for their in vitro cytotoxicity employing a panel of different human tumor cell lines, A375, HT29, MCF7, A2780, FaDu as well as non-malignant NIH 3T3 and HEK293 cells. It has been found that the pyrazolo-pyrido-pyrimidine analog bearing a 4-Br-phenyl moiety was the most active toward many cell lines with EC50 values ranging between 9.1 and 13.5 µM. Moreover, in silico docking studies of the latter with six anticancer drug targets, i.e., DHFR, VEGFR2, HER-2/neu, hCA-IX, CDK6 and LOX5, were also performed, in order to gain some insights into their putative mode of binding interaction and to estimate the free binding energy of this bioactive molecule.
