Enhanced delivery of biodegradable mPEG-PLGA-PLL nanoparticles loading Cy3-labelled PDGF-BB siRNA by UTMD to rat retina

We investigated the efficacy and safety of ultrasound (US)-targeted microbubble (MB) destruction (UTMD)-enhanced delivery of monomethoxypoly(ethylene glycol)-poly(lactic-co-glycolic acid)-poly-l-lysine (mPEG-PLGA-PLL) nanoparticles (NPs) loading Cy3-labelled platelet-derived growth factor BB (PDGF-BB) siRNA to rat retina in vivo. Eighty Wistar rats were divided into five groups (G). The right eyes, respectively, received an intravitreal injection as follows: normal saline (NS) (G1), NPs and NS (G2), NPs and MBs (G3), NPs and NS (G4) and NPs and MBs (G5). In G4 and G5, the eyes were exposed to US for 5 mins. Twenty-four hours after transfection, the uptake and distribution of Cy3-labelled siRNA in rat retina were observed by fluorescent microscope. The percentage of Cy3-labelled siRNA-positive cells was evaluated by flow cytometer. The levels of PDGF?BB mRNA in retinal pigment epithelium (RPE) cells and secreted PDGF?BB proteins were also measured. Hematoxylin and eosin staining and frozen sections were used to observe tissue damage. Our results showed that the number of Cy3-labelled siRNA-positive cells in G5 was significantly higher than those of the other groups (P<0.05 for all comparisons). The maximum efficiency of siRNA uptake in neural retina was 18.22¡À1.67%. In G4 and G5, a small number of Cy3-labelled siRNA-positive cells were also detected in the pigmented cell layer of the retina. NPs loading siRNA delivered with UTMD could more effectively down-regulate the mRNA and protein expression of PDGF?BB than NPs plus US (P=0.014 and P=0.007, respectively). Histology showed no evident tissue damage after UTMD-mediated NPs loading siRNA transfection. UTMD could be used safely to enhance the delivery of mPEG-PLGA-PLL NPs loading siRNA into rat retina.

Fluorinated indole-imidazole conjugates: Selective orally bioavailable 5-HT7 receptor low-basicity agonists, potential neuropathic painkillers

The 5-HT7 receptor has recently gained much attention due to its involvement in multiple physiological functions and diseases. The insufficient quality of the available molecular probes prompted design of fluorinated 3-(1-alkyl-1H-imidazol-5-yl)-1H-indoles as a new generation of selective 5-HT7 receptor agonists. A potent and drug-like agonist, 3-(1-ethyl-1H-imidazol-5-yl)-5-iodo-4-fluoro-1H-indole (AGH-192, 35, Ki 5-HT7R = 4 nM), was identified by optimizing the halogen bond formation with Ser5.42 as the supposed partner. The compound was characterized by excellent water solubility, high selectivity over related CNS targets, high metabolic stability, oral bioavailability and low cytotoxicity. Rapid absorption into the blood, medium half-life and a high peak concentration in the brain Cmax = 1069 ng/g were found after i.p. (2.5 mg/kg) administration in mice. AGH-192 may thus serve as the long-sought tool compound in the study of 5-HT7 receptor function, as well as a potential analgesic, indicated by the antinociceptive effect observed in a mouse model of neuropathic pain.

Design and synthesis of pyrrolo[3,2- d ]pyrimidine human epidermal growth factor receptor 2 (HER2)/epidermal growth factor receptor (EGFR) dual inhibitors: Exploration of novel back-pocket binders

To develop novel human epidermal growth factor receptor 2 (HER2)/epidermal growth factor receptor (EGFR) kinase inhibitors, we explored pyrrolo[3,2-d]pyrimidine derivatives bearing bicyclic fused rings designed to fit the back pocket of the HER2/EGFR proteins. Among them, the 1,2-benzisothiazole (42m) ring was selected as a suitable back pocket binder because of its potent HER2/EGFR binding and cell growth inhibitory (GI) activities and pseudoirreversibility (PI) profile as well as good bioavailability (BA). Ultimately, we arrived at our preclinical candidate 51m by optimization of the N-5 side chain to improve CYP inhibition and metabolic stability profiles without a loss of potency (HER2/EGFR inhibitory activity, IC50, 0.98/2.5 nM; and GI activity BT-474 cells, GI50, 2.0 nM). Reflecting the strong in vitro activities, 51m exhibited potent tumor regressive efficacy against both HER2- and EGFR-overexpressing tumor (4-1ST and CAL27) xenograft models in mice at oral doses of 50 mg/kg and 100 mg/kg.

Design, synthesis and biological evaluation of quinoline-indole derivatives as anti-tubulin agents targeting the colchicine binding site

A series of novel isocombretastatin A-4 (isoCA-4) analogs were designed and synthesized by replacing 3,4,5-trimethoylphenyl and isovanillin of isoCA-4 with quinoline and indole moieties, respectively. The structure activity relationships (SARs) of these synthesized quinoline-indole derivatives have been intensively investigated. Two compounds 27c and 34b exhibited the most potent activities against five cancer cell lines with IC50 values ranging from 2 to 11 nM, which were comparable to those of Combretastatin A-4 (CA-4, 1). Further mechanism investigations revealed that 34b effectively inhibited the microtubule polymerization by binding to the colchicine site of tubulin. Further cellular mechanism studies elucidated that 34b disrupted cell microtubule networks, arrested the cell cycle at G2/M phase, induced apoptosis and depolarized mitochondria of K562 cells. Moreover, 34b displayed potent anti-vascular activity in both wound healing and tube formation assays. Importantly, 27c and 34b significantly inhibited tumor growth in H22 xenograft models without apparent toxicity, suggesting that 27c and 34b deserve further research as potent antitumor agents for cancer therapy.

Pharmacokinetics of N-ethylpentylone and its effect on increasing levels of dopamine and serotonin in the nucleus accumbens of conscious rats

N-Ethylpentylone (NEP) is one of the most confiscated synthetic cathinones in the world. However, its pharmacology and pharmacokinetics remain largely unknown. In this study, the pharmacokentics of NEP in rat nucleus accumbens (NAc) was assessed via brain microdialysis after the intraperitoneal (ip) administration of NEP (20 or 50?mg/kg). The concentrations of dopamine (DA) and serotonin (5-HT) and their metabolites, including 3,4-dihydroxyphenylacetic acid (DOPAC), 3-methoxytyramine (3-MT), and 5-hydroxyindoleacetic acid (5-HIAA), were simultaneously monitored to elucidate the pharmacological effect of NEP. In addition, the plasma levels of NEP were also assessed. The pharmacokinetics of NEP showed a dose-related pattern, with NEP rapidly passing through the blood-brain barrier and reaching a maximum concentration (Cmax) at approximately 40-minutes postdose. Approximately 4% of plasma NEP was distributed to the NAc, and considering a homogeneous brain distribution, over 90% of plasma NEP was potentially distributed to the brain. High values of area under curve (AUC) and mean residence time (MRT) of NEP were observed in both the NAc and plasma, indicating large and long-lasting effects. NEP elicited dose-related increases in microdialysate DA and 5-HT and increased the concentration of 3-MT in a dose-related manner. However, the rate of DA converted into 3-MT was unaffected. NEP had a negative effect on the rates of which DA and 5-HT were transformed into DOPAC and 5-HIAA, respectively. In summary, NEP rapidly entered the NAc and showed a long-lasting effect. In addition, DA increased more significantly than 5-HT, indicating a large potential for NEP abuse.

7-Deazaguanine modifications protect phage DNA from host restriction systems

Genome modifications are central components of the continuous arms race between viruses and their hosts. The archaeosine base (G+), which was thought to be found only in archaeal tRNAs, was recently detected in genomic DNA of Enterobacteria phage 9g and was proposed to protect phage DNA from a wide variety of restriction enzymes. In this study, we identify three additional 2?-deoxy-7-deazaguanine modifications, which are all intermediates of the same pathway, in viruses: 2?-deoxy-7-amido-7-deazaguanine (dADG), 2?-deoxy-7-cyano-7-deazaguanine (dPreQ0) and 2?-deoxy-7- aminomethyl-7-deazaguanine (dPreQ1). We identify 180 phages or archaeal viruses that encode at least one of the enzymes of this pathway with an overrepresentation (60%) of viruses potentially infecting pathogenic microbial hosts. Genetic studies with the Escherichia phage CAjan show that DpdA is essential to insert the 7-deazaguanine base in phage genomic DNA and that 2?-deoxy-7-deazaguanine modifications protect phage DNA from host restriction enzymes.
