Pharmacokinetics and Biodistribution of Pegylated Methotrexate after IV Administration to Mice
The efficacy of methotrexate (MTX) as an antimetabolite chemotherapeutic agent highly depends on its blood circulation half-life. In our previous study, different conjugates of MTX (MTX-PEG) were synthesized, their physicochemical properties were investigated and MTX-PEG5000 was finally selected as optimum drug-conjugate for further investigations. In the current work, first the stability of MT...
متن کاملAntibacterial activity and cytotoxicity of PEGylated poly(amidoamine) dendrimers.
We have investigated the antibacterial activity and cytotoxicity of a series of amino-terminated poly(amidoamine) (PAMAM) dendrimers modified with poly(ethylene glycol) (PEG) groups. The antibacterial activity of the PAMAM dendrimers and their derivatives against the common ocular pathogens, Pseudomonas aeruginosa and Staphylococcus aureus, was evaluated by their minimum inhibitory concentratio...

متن کاملMethotrexate-conjugated PEGylated dendrimers show differential patterns of deposition and activity in tumor-burdened lymph nodes after intravenous and subcutaneous administration in rats.
The current study sought to explore whether the subcutaneous administration of lymph targeted dendrimers, conjugated with a model chemotherapeutic (methotrexate, MTX), was able to enhance anticancer activity against lymph node metastases. The lymphatic pharmacokinetics and antitumor activity of PEGylated polylysine dendrimers conjugated to MTX [D-MTX(OH)] via a tumor-labile hexapeptide linker w...
متن کاملInteraction of Poly-l-lysine with Chromatin
The priming capacity of chromatin of fixed nuclei and chromosomes for exogenous DNA polymerase can be evaluated radioautographically by the incorporation of labeled nucleotides. It had previously been reported that acid fixation or acid treatment of alcohol-fixed tissues led to increased priming when calf thymus DNA polymerases, specific for single-stranded DNA, were used. We employed Escherich...
