Density functional theory (DFT) calculations were performed on tripeptide arginyl-glycyl-aspartic acid (RGD) as an efficient drug carrier to deliver the commercially famous cyclophosphamide (CP) anticancer drug within ethanol solution. The most negative binding energy (-5.22 kcal/mol) was measured for the CP-RGD-7 created through the H-bond interaction between the P=O (phosphoryl) oxygen atom o...
Background: Eptifibatide (Integrilin®) is a hepta-peptide drug which specifically prevents the aggregation of activated platelets. The peptide drugs are encapsulated into nanolipisomes in order to decreasing their side effects and improving their half-life and bioavailability. Objectives: In this study, the in vitro cytotoxicity and hemocompatibi...
Abstract Background The development of alternative anti-angiogenesis therapy for choroidal neovascularization (CNV) remains a great challenge. Nanoparticle systems have emerged as new form drug delivery in ocular diseases. Here, we report the construction and characterization arginine-glycine-aspartic acid (RGD)-conjugated polyethyleneimine (PEI) vehicle to load antioxidant salvianolic A (SAA) ...
Objective(s): Up to now, many researches have been performed to improve the antitumoral effect of melanoma differentiation-associated gene-7 (mda-7) protein. The purpose of our research was to construct 3 expression vectors producing mda-7 in fusion with RGD (Arginine-Glycine-Aspartic acid) peptide and evaluate their expression. Materials and Methods: mda-7 gene with two different RGD sequ...
BACKGROUND Expression of αvβ3 integrin is increased after myocardial infarction as part of the repair process. Increased expression of αvβ3 has been shown by molecular imaging with 18F-galacto-RGD in a rat model. The 68Ga-labelled RGD compounds 68Ga-NODAGA-RGD and 68Ga-TRAP(RGD)3 have high specificity and affinity, and may therefore serve as alternatives of 18F-galacto-RGD for integrin imaging....
PURPOSE The purpose of this study was to demonstrate the valence of cyclic RGD peptides, P-RGD (PEG(4)-c(RGDfK): PEG(4) = 15-amino-4,710,13-tetraoxapentadecanoic acid), P-RGD(2) (PEG(4)-E[c(RGDfK)](2), 2P-RGD(4) (E{PEG(4)-E[c(RGDfK)](2)}(2), 2P4G-RGD(4) (E{PEG(4)-E[G(3)-c(RGDfK)](2)}(2): G(3) = Gly-Gly-Gly) and 6P-RGD(4) (E{PEG(4)-E[PEG(4)-c(RGDfK)](2)}(2)) in binding to integrin α(v)β(3), and ...
Molecular interactions between RGD peptides and integrins are known to mediate many biological and pathological processes. This has led to an increased interest in the development of RGD compounds with high affinity and improved selectivity for integrin receptors. In this study, we synthesized and evaluated a series of multimeric RGD compounds constructed on a dicarboxylic acid-containing near-...
PURPOSE Truncated tissue factor (tTF) fusion protein targeting tumor vasculature can induce tumor vascular thrombosis and necrosis. Here, we generated (RGD)₃-tTF in which three arginine-glycine-aspartic (RGD) targeting integrin α(v)β₃ and tTF induce blood coagulation in tumor vessels. METHODS The bioactivities of (RGD)₃-tTF including coagulation activity, FX activation, and binding with integ...
In order to understand the relationship between sequences and biological functions of RGD-containing wild silkworm silk fibroin, it is important to purify the basic RGD-containing motif in large quantities. In this study, a gene monomer encoding RGD-contained motif GSGAGGRGDGGYGSGSS (-RGD-) derived from Antheraea pernyi (the same in Antheraea yamamai) was designed and cloned. (-RGD-)n in variou...
Macrophage Adhesions In article number 2215166, Heemin Kang, Jong Seung Kim, and co-workers report the magnetic control of bridging non-bridging between RGD-coated nanomaterials non-magnetic RGD nanomaterials. This variable in situ temporally modulates recruitment, integrin binding, adhesion structure assembly host macrophages that determine their functional pro-inflammatory or pro-healing immu...
