Pancreatic cancer is one of the most malignant tumor diseases with the characters of aggressive growth and metastasis. With the inefficiency of the current therapeutics, new potential targets and new therapeutic agents for healing of pancreatic cancer are critically needed. We have previously found a small molecule, named 4-tert-butyl-2-[(cyclohexylamino)(More)
We report here the investigation of a novel description of specificity in protein-ligand binding based on energy landscape theory. We define a new term, intrinsic specificity ratio (ISR), which describes the level of discrimination in binding free energies of the native basin for a protein-ligand complex from the weaker binding states of the same ligand. We(More)
The identification and application of druggable pockets of targets play a key role in in silico drug design, which is a fundamental step in structure-based drug design. Herein, some recent progresses and developments of the computational analysis of pockets have been covered. Also, the pockets at the protein–protein interfaces (PPI) have been considered to(More)
Pancreatic cancer is considered a lethal and treatment-refractory disease. To obtain a potent anticancer drug, the cytotoxic effect of 2-(benzo[d]oxazol-3(2H)-ylmethyl)-5-((cyclohexylamino)methyl)benzene-1,4-diol, dihydrochloride (NSC48693) on human pancreatic cancer cells CFPAC-1, MiaPaCa-2, and BxPC-3 was assessed in vitro. The proliferation of CFPAC-1,(More)
Computer-aided drug design (CADD) plays significant roles in all stages of today's drug discovery. Many CADD technologies and methods were employed in finding promising hits against different targets during the past several decades. In this review, the most common molecular modeling methods applied to computer-aided drug design are discussed. However, how(More)
The affinity and specificity of drugs with human serum albumin (HSA) are crucial factors influencing the bioactivity of drugs. To gain insight into the carrier function of HSA, the binding of levamlodipine with HSA has been investigated as a model system by a combined experimental and theoretical/computational approach. The fluorescence properties of HSA(More)
Here, we present the crystal structure of the ecdysone phosphate phosphatase (EPPase) phosphoglycerate mutase (PGM) homology domain, the first structure of a steroid phosphate phosphatase. The structure reveals an alpha/beta-fold common to members of the two histidine (2H)-phosphatase superfamily with strong homology to the Suppressor of T-cell receptor(More)
Thymopentin (TP5) triggers an immune response by contacting with T cells; however the molecular basis of how TP5 achieves this process remains incompletely understood. According to the main idea of immunomodulation, we suppose that it would be necessary for TP5 to form complex with human class II major histocompatibility complex DR molecules (HLA-DR) before(More)
PREMISE OF THE STUDY Microsatellite markers were developed in Myrica rubra to investigate potential hybridization events within or between M. rubra and its closely related species. METHODS AND RESULTS Using an ISSR-suppression PCR method, 12 primer pairs were temporarily developed with GSG(GT)(6) as the primer for enriching microsatellite sequences and(More)
