Thermally reactive N-(2-Hydroxypropyl)methacrylamide (HPMA) amphiphiles for drug solubilisation
Int J Pharm 2021 May 15;601:120570.PMID:33812968DOI:10.1016/j.ijpharm.2021.120570.
Thermally active polymers, can respond structurally to temperature changes, making them interesting as potential drug delivery vehicles. Polymers of N-(3-aminopropyl) methacrylamide hydrochloride (APMA) are cationic with primary amine groups in their structure, which have been explored in biomedical applications via post-polymerisation modifications. In this work, we synthesised amphiphilic APMA monomers using hydrophobic pendant groups via conjugation onto their primary amine group. The pendant groups chosen in this study were palmitoyl, dansyl and cholesteryl moieties. The amphiphilic monomers were subsequently copolymerized with N-(2-Hydroxypropyl)methacrylamide (HPMA) using varied monomer feed ratios resulting in a thermo-responsive system. The ability of the resultant aggregates in aqueous solution to encapsulate and liberate model drugs (e.g., propofol, griseofulvin and prednisolone) was then determined. Our data showed that the HPMA based formulations were capable of loading the model drug molecules inside their lipophilic core; HPMA-co-(APMA-Dansyl 2%) exhibited the largest drug encapsulation ability. Subsequently, poly(ethylene glycol) (PEG) was incorporated into the intrinsic polymer structure. This resulted in a more rapid drug release profile, whereby 100% of griseofulvin and prednisolone were liberated after only 4 h, which was only 5% and 10% before the PEG inclusion, respectively. Similarly, propofol showed 70% liberation from the polymer aggregate after 24 h, compared with only 30% liberation pre-PEGylation. These studies give an insight into the potential of the HMPA based amphiphiles as thermally responsive cargo carrier/release systems which could be exploited in the delivery of poorly soluble drugs.
Clinical implications of N-(2-Hydroxypropyl)methacrylamide copolymers
Curr Pharm Biotechnol 2003 Oct;4(5):311-22.PMID:14529421DOI:10.2174/1389201033489711.
Different anticancer drugs, farmorubicin, doxorubicin, paclitaxel and cis-platin have been conjugated through a Gly-Phe-Leu-Gly tetrapeptide side chain to a water-soluble synthetic polymeric carrier based on N-(2-hydroxypropyl)methacryalmide (HPMA) non-targeted or targeted with galactosamine and/or human IVIg and used in Phase I clinical trials. Conjugation of the drugs to the polymeric carrier that is non-toxic and non-immunogenic in man significantly decreased their non-specific organ toxicities and increased maximum tolerated dose up to 5 times. Macromolecular therapeutics based on HPMA have radically different pharmacokinetics. Drugs are not released from their polymeric carrier and remain in the peripheral blood and urine of patients mostly in their polymer-bound form. A clinical response against some refractory cancers was recorded in Phase I clinical trials. It was also demonstrated that doxorubicin-HPMA copolymer conjugates containing an immunoglobulin moiety have both cytostatic and immunomobilizing activity.
Poly[N-(2-Hydroxypropyl)methacrylamide]-Modified Magnetic γ-F2 O3 Nanoparticles Conjugated with Doxorubicin for Glioblastoma Treatment
ChemMedChem 2020 Jan 7;15(1):96-104.PMID:31670889DOI:10.1002/cmdc.201900564.
With the aim to develop a new anticancer agent, we prepared poly[N-(2-hydroxypropyl)methacrylamide-co-methyl 2-methacrylamidoacetate] [P(HP-MMAA)], which was reacted with hydrazine to poly[N-(2-hydroxypropyl)methacrylamide-co-N-(2-hydrazinyl-2-oxoethyl)methacrylamide] [P(HP-MAH)] to conjugate doxorubicin (Dox) via hydrazone bond. The resulting P(HP-MAH)-Dox conjugate was used as a coating of magnetic γ-Fe2 O3 nanoparticles obtained by the coprecipitation method. In vitro toxicity of various concentrations of Dox, P(HP-MAH)-Dox, and γ-Fe2 O3 @P(HP-MAH)-Dox nanoparticles was determined on somatic healthy cells (human bone marrow stromal cells hMSC), human glioblastoma line (GaMG), and primary human glioblastoma (GBM) cells isolated from GBM patients both at a short and prolonged exposition time (up to 7 days). Due to hydrolysis of the hydrazone bond in acid milieu of tumor cells and Dox release, the γ-Fe2 O3 @P(HP-MAH)-Dox nanoparticles significantly decreased the GaMG and GBM cell growth compared to free Dox and P(HP-MAH)-Dox in low concentration (10 nM), whereas in hMSCs it remained without effect. γ-F2 O3 @PHP nanoparticles alone did not affect the viability of any of the tested cells.
High-Affinity N-(2-Hydroxypropyl)methacrylamide Copolymers with Tailored N-Acetyllactosamine Presentation Discriminate between Galectins
Biomacromolecules 2020 Feb 10;21(2):641-652.PMID:31904940DOI:10.1021/acs.biomac.9b01370.
N-Acetyllactosamine (LacNAc; Galβ4GlcNAc) is a typical disaccharide ligand of galectins. The most abundant members of these human lectins, galectin-1 (Gal-1) and galectin-3 (Gal-3), participate in a number of pathologies including cancerogenesis and metastatic formation. In this study, we synthesized a series of fifteen N-(2-Hydroxypropyl)methacrylamide (HPMA)-based glycopolymers with varying LacNAc amounts and presentations and evaluated the impact of their architecture on the binding affinity to Gal-1 and Gal-3. The controlled radical reversible addition-fragmentation chain transfer copolymerization technique afforded linear polymer precursors with comparable molecular weight (Mn ≈ 22,000 g mol-1) and narrow dispersity (D̵ ≈ 1.1). The precursors were conjugated with the functionalized LacNAc disaccharide (4-22 mol % content in glycopolymer) prepared by enzymatic synthesis under catalysis by β-galactosidase from Bacillus circulans. The structure-affinity relationship study based on the enzyme-linked immunosorbent assay revealed that the type of LacNAc presentation, individual or clustered on bi- or trivalent linkers, brings a clear discrimination (almost 300-fold) between Gal-1 and Gal-3, reaching avidity to Gal-1 in the nanomolar range. Whereas Gal-1 strongly preferred a dense presentation of individually distributed LacNAc epitopes, Gal-3 preferred a clustered LacNAc presentation. Such a strong galectin preference based just on the structure of a multivalent glycopolymer type is exceptional. The prepared nontoxic, nonimmunogenic, and biocompatible glycopolymers are prospective for therapeutic applications requiring selectivity for one particular galectin.
N-(2-Hydroxypropyl)methacrylamide Copolymer-Drug Conjugates for Combination Chemotherapy of Acute Myeloid Leukemia
Macromol Biosci 2016 Jan;16(1):121-8.PMID:26222892DOI:10.1002/mabi.201500193.
There is a need for new treatment strategies of acute myeloid leukemia (AML). In this study, four different drugs, including cytarabine, daunorubicin, GDC-0980, and JS-K, were investigated in vitro for the two-drug combinations treatment of AML. The results revealed that cytarabine and GDC-0980 had the strongest synergism. In addition, cell cycle analysis was conducted to investigate the effect of the different combinations on cell division. For future in vivo application, N-(2-Hydroxypropyl)methacrylamide (HPMA) copolymer-cytarabine and GDC-0980 conjugates were synthesized, respectively. In vitro studies demonstrated that both conjugates had potent cytotoxicity and their combination also showed strong synergy, suggesting a potential chemotherapeutic strategy for future AML treatment.
