AbstractThree BODIPY ‐peptide conjugates designed to target the epidermal growth factor receptor (EGFR) at the extracellular domain were synthesized and their specificity for binding to EGFR was investigated. Peptide sequences containing seven amino acids, GLARLLT (2) and KLARLLT (3), and 13 amino acids, GYHWYGYTPQNVI (4), were conjugated to carboxyl BODIPY dye (1) by amide bond formation in up to 73% yields. The BODIPY ‐peptide conjugates and their “parent” peptides were determined to bind to EGFR experimentally using SPR analysis, and were further investigated using computational methods (AUTODOCK). Resul...

ConclusionCompounds 1, 2, 5, and 6 showed anti-prostate cancer activities using the LNCaP prostate cancer cells with IC50 values of 17.84, 33.26, 54.13, and 81.55 μg/mL, and compounds 3, 4, 8, and 9 exhibited moderate hepatoprotective activities, respectively. A preliminary structure-activity relation was summarized in this paper.Graphical abstract

Authors: Gholami A, Mousavi SM, Hashemi SA, Ghasemi Y, Chiang WH, Parvin N Abstract Nowadays, magnetic nanoparticles (MNPs) have been rapidly investigated and attracted worldwide attention due to their great potential as mediators of heat for treating hyperthermia and their possibility to deliver drugs at specific locations, which can thereby limit systematic effects. Cancer therapy via MNPs proposes novel properties rather than normal methods such as almost zero side effects and a high-efficiency rate of effectiveness. The key aim of targeted drug delivery is to reduce side effects of the main cancer treatment tha...

In this study we tried to explore Diazepam as a repurposed drug and tested it in Neuroblastoma (Neuro 2a) cells. Diazepam loaded Poly Lactic Acid Nanoparticles were developed (D-PLA-NPs) using nanoprecipitation method. Entrapment efficiency was found to be ± 99.7% and drug loading was ± 12.88%. The particle size developed was 188.8 nm and zeta potential was −25.6 millivolt. Dissolution profiles were studied in PBS (pH 7.4) or simulated media, almost 50% release was observed within 6 h. In vitro, cytotoxicity was analyzed using MTT assay where dose-dependent cytotoxicity was observed for developed D-PLA-NPs.

Abstract Two novel electrochemiluminescence (ECL) deoxyribosensors are designed for assay of early lung cancer biomarker (NAP2) using the DNA three-way junction (DNA-TWJ) inserted NAP2 binding aptamer between two double-helical stems and labeled with ruthenium (II) complex (Ru) (NBAT-Ru) taken as molecular recognition element. The signal-off ECL deoxyribosensor was fabricated by covalently coupling the 5'-NH2-(CH2)6-NBAT-Ru to glassy carbon electrode surface modified with 4-aminobenzoic acid (4-ABA). After combining NAP2 and NBAT-Ru, the changed conformation of NBAT-Ru altered the distance between Ru complex and e...

Abstract The expression level of miRNA-21 is closely related to the occurrence and development of cancer, especially in gastrointestinal cancer. Monitoring miRNA-21 has clinical application in the diagnosis and evaluation of gastrointestinal cancer. A turn-on ratiometric fluorescence bioassay based on the T7 exonuclease-mediated cyclic enzymatic amplification method was developed for miRNA-21 determination by using carbon dots (CDs) and FAM-labeled ssDNA as the signal source. CDs demonstrated the triple functions of built-in internal fluorescence, probe carrier, and quencher in this strategy. In the absence of miR...

Abstract Development of a mitochondria-targeting fluorescent probe with large Stokes shift and long-wavelength emission was benefit for accurate detection of hypoxic status, which was known as a major factor of the tumor physiology and influence important pathological processes. However, an efficient optical approach for simultaneously achieving such merits was still lacking. In this work, a turn-on fluorescence probe (HBT-NP) was designed to assess the hypoxic condition of tumor cells by detecting nitroreductase (NTR). Probe HBT-NP was constructed by conjugating 4-nitrobenzyl moiety as reaction site for NTR to 2-...
