targeted drug delivery to cancer stem cells by hyaluronic acid-based drug conjugates: synthesis and characterization

Gold nanoparticles stabilize peptide-drug-conjugates for sustained targeted drug delivery to cancer cells

BACKGROUND Peptide-drug-conjugates (PDCs) are being developed as an effective strategy to specifically deliver cytotoxic drugs to cancer cells. However one of the challenges to their successful application is the relatively low stability of peptides in the blood, liver and kidneys. Since AuNPs seem to have a longer plasma half-life than PDCs, one approach to overcoming this problem would be to ...

Automated Modular Synthesis of Aptamer–Drug Conjugates for Targeted Drug Delivery

Aptamer-drug conjugates (ApDCs) are promising targeted drug delivery systems for reducing toxicity while increasing the efficacy of chemotherapy. However, current ApDC technologies suffer from problems caused by the complicated preparation and low controllability of drug-aptamer conjugation. To solve such problems, we have designed and synthesized a therapeutic module for solid phase synthesis,...

Formulation of temozolomide by folic acid-conjugated tri-block copolymer nanoparticles for targeted drug delivery

Introduction: Glioblastoma multiforme (GBM) is the most frequent primary malignant tumor of the brain. But, the treatment of GBM is one of the most problems in cancer therapy because of poor drug penetration across the blood-brain barrier (BBB). Targeting drug delivery system and conjugating targeting moieties was recognized to overcome the poor penetration of chemotherapy drug...

Doxorubicin Loaded DNA Aptamer Linked Myristilated Chitosan Nanogel for Targeted Drug Delivery to Prostate Cancer

Recently, specific attention has been paid to aptamers, short DNA or RNA, as a tool for cancer diagnosis and therapy. In the present study MCS nanogels were prepared by Myristate: chitosan at 1:9 ratio and were characterized by several techniques. A selected ssDNA aptamer(Apt) capable of detecting LNCaP cells was linked to Myristilated chitosan nanogels (Apt-MCS) by glutaraldehyde and loaded wi...
