Abstract:

Lipoprotein-based technologies could address many of the concerns of traditional chemotherapy via their ability to selectively deliver their payload to cancer cells and tumors via a receptor-mediated mechanism. Moreover, they have been shown to be equally effective for targeted diagnostic imaging. Specifically, it has been shown that malignant cells consistently overexpress Scavenger receptor class B type 1 (SR-B1) receptors compared to normal cells which are the receptor for lipoprotein based nanoparticles. The therapeutic index of many cytotoxic drugs can thus be significantly improved by enhancing the selective delivery and accumulation of the therapeutic agent in malignant cells and tumors vs. healthy cells and tissue, thus avoiding toxic side effects. Lipoprotein-based nanoparticles have the potential to perform tumor selective delivery and thus overcome these limitations. We will present some of our recent findings and progress in the area of lipoprotein drug delivery. Consequently, reconstituted (synthetic) lipoproteins have proven to be a superior biocompatible drug-delivery platform and thus have great potential for cancer theranostics.

Abstract:

Zingiberaceous plants have been used in traditional medicines throughout the tropical countries. The Zingiberaceae is rich in flavonoids especially quercetin and its derivatives. Flavonoids are potent antioxidant compounds with excellent anticancer activity. Inhibition of multidrug resistant cancer cell growth and MDR transporter by flavonoids has been reported. In this study, the water-insoluble quercetin was loaded into mPEG-b-OCL-Bz micelles. The average particle size of quercetin-loaded mPEG-b-OCL-Bz micelles was around 14-20nm with a maximum loading capacity of 7.3%. Besides, quercetin incorporated polymeric micelles are stable for 14 days at 37℃. The cytotoxicity results of this study reveal that the similar cell growth inhibition on sensitive and resistant leukemia cells was found from both free quercetin and quercetin loaded micelles which suggested that free quercetin and quercetin-loaded micelles were not transported by P-glycoprotein. Interestingly, QCT-loaded micelles increased the efficacy of the cytotoxicity of chemotherapeutic drugs (doxorubicin and daunorubicin) indicating that QCT-loaded micelle can reverse the function of P-glycoprotein. Finally, the determination of the kinetics of P-glycoprotein found that the efflux of pirarubicin was modulated by quercetin-loaded micelles in a dose-dependent manner and non-competitive mechanism. These results demonstrated that mPEG-b-OCL-Bz micelles are a promising carrier for overcoming multidrug resistance cancer.

Abstract:

Introduction: Stroke is one of the leading causes of mortality and disability. Clinical studies conducted in patients with a recent ischemic stroke and treated with policosanol (20mg/day)+standard aspirin (AS) (125mg/day) therapy have shown benefits versus placebo+AS to patients with recent ischemic stroke.

Objectives: The objective of the present paper is to a preliminary retrospective analysis of the policosanol treatment effects in the patients included in ischemic stroke recovery trials.

Methods: This report analyzed the records of all patients included in four ischemic stroke recovery studies. Patients with a modified Rankin Scale score (mRSs) 2 to 4 were randomized, within 30 days of onset, to policosanol+AS or placebo+AS, for 6 and 12 months. The primary outcome was an mRSs reduction. Decreases on low-density lipoprotein-cholesterol (LDL-C), total cholesterol and increases on high-density lipoprotein-cholesterol (HDL-C) were secondary outcomes.

Results: Two hundred and seventy-one patients (mean age: 67 years) were included in the analysis. At the six months more policosanol+AS (117/136, 86%) than placebo+AS patients (10/135, 7.3%) achieved mRSs goals. In correspondence, at the 12 months of the study more policosanol+AS (50/59, 84.7%) than placebo+AS patients (5/59, 8.5%) achieved mRSs goals. Treatment with policosanol+AS significantly decreased mean mRSs from the first interim check-up. The treatment effect did not wear off, even improved, after 6 and 12 months therapy when the net decrease versus placebo+AS was 56% and 70.8%, respectively. In addition, policosanol+AS reduced significantly LDL-C (21.6%) and total cholesterol (12.5%), and increased HDL-C (6.3%). Treatments were safe and well tolerated. Eight patients reported serious adverse events (6 placebo+AS, 2 policosanol+AS) and other 13 patients (8 placebo+AS, 5 policosanol+AS) reported moderate or mild adverse events.

Conclusions: The preliminary retrospective analysis of the effects of policosanol+AS on ischemic stroke patients indicate that this treatment for 6 and 12 months proved to be more effective than the placebo+AS treatment in the functional recovery of these patients.

Abstract:

To develop nucleic-acid based nanocarrier for cytotoxic-drug through self-assembly of designed sequences of artificial DNA-strands. Cisplatin having DNA binding ability is loaded in DNA-NT with the aim to achieve enhanced cytotoxicity and cell-internalization mediated by scavenger receptors targeted into Human cervical cancer cells (Hela). DNA nanothread (NT) synthesized by self-assembly of triangular-tiles made from annealing staple-strands with the circularized scaffold-strand. DNA-NT structures and integrity characterized by AFM and Native-PAGE. Cisplatin binding to the DNA-NT confirmed by UV-shift. The biocompatibility of DNA-NT and in-vitro cytotoxic studies of Cisplatin/DNA-NT assessed by MTT. Flow cytometry to quantify the effects of Cisplatin/DNA on cell-cycle phase arrest and apoptosis. The internalization of Cisplatin/DNA-NT in the cells was imaged by confocal microscopy. AFM results showed uniform DNA nanothread structures with a diameter ranging from 50 to 150nm with 300 to 600nm length. Strength/integrity of DNA nanothread was evaluated through PAGE (native), DNA nanothread being stable structure did not split into constituting strands. The results of cell viability confirmed that blank DNA-NT had the least cytotoxicity at the highest concentration with the retained value of 92% as evidence to be biocompatible nanocarrier for drug delivery. While in-vitro cytotoxicity assessment of Cisplatin/DNA-NT displayed increased anticancer activity. Flow cytometry experiments with the Cisplatin/DNA-NT increased the percentage of apoptotic cells significantly in a dose-dependent manner. Moreover, in Confocal microscopy assay, Cisplatin loaded DNA nanothread seems to efficiently deliver Cisplatin to the Hela cell nuclei. Circular DNA nanotechnology is a tool to design architects with stiffer topology and geometry based on Watson-Crick base pairing for potential applications including drug delivery. We find that being poly-anionic nature, Cisplatin/DNA-NT show enhanced endocytosis via scavenger receptors causing intracellular drug release and enhanced cytotoxicity, which boost the cancer targeting and therapy.

Abstract:

Native gums may be limited in function, but modification may improve their activity. The objective of the present study was to evaluate the native and modified form of Cordia myxa gum for its sustained release and mucoadhesive properties. Modification of natural Cordia myxa polysaccharide was done using sulfation technique. The modified polymer was evaluated for mucoadhesive characteristics with systematic optimization by central composite experimental designing. The tablets prepared with modified polymer were compared with native polymer and Carbopol 934. The mucoadhesive tablets of Losartan Potassium were evaluated for various parameters such as weight variation, hardness, friability, drug content, content uniformity, mucoadhesion strength, in-vitro release characteristics and in-vivo gastric retention study. Modification improved the gum's flow properties, resulting in Carr's index and Hausner's ratio lower than 15% and 1.25, respectively. Swelling studies showed that modified gum had lower water absorption capacity and swelling index values while packing properties improved upon sulfation, indicated by lower tapped density values. Modification of the gum was confirmed by FTIR, DSC and 1H NMR. The gum's mucoadhesive properties were improved and sustained release action of 24h was obtained. Sulfation of native Cordia myxa gum improved the flow, mechanical and sustained-release properties of Losartan Potassium tablets. The results suggested that sulfation of Cordia myxa gum proved to be a successfully employed method for formulation of mucoadhesive drug delivery systems to alleviate the drawbacks of the conventional delivery of the drugs in the management of hypertension thereby improving the patient compliance.
