Antisense oligonucleotide development for the selective modulation of CYP3A5 in renal disease
ABSTRACT CYP3A5 is the primary CYP3A subfamily enzyme expressed in the human kidney and its aberrant expression may contribute to a broad spectrum of renal disorders. Pharmacogenetic studies have reported inconsistent linkages between CYP3A5 expression and hypertension, however, most investigators have considered CYP3A5*1 as active and CYP3A5*3 as an inactive allele. Observations of gender specificRead More
siRNAs containing 2′-fluorinated Northern-methanocarbacyclic (2′-F-NMC) nucleotides: in vitro and in vivo RNAi activity and inability of mitochondrial polymerases to incorporate 2′-F-NMC NTPs
ABSTRACT We recently reported the synthesis of 2′-fluorinated Northern-methanocarbacyclic (2′-F-NMC) nucleotides, which are based on a bicyclo[3.1.0]hexane scaffold. Here, we analyzed RNAi-mediated gene silencing activity in cell culture and demonstrated that a single incorporation of 2′-F-NMC within the guide or passenger strand of the tri-N-acetylgalactosamine-conjugated siRNA targeting mouse Ttr was generally well tolerated. Exceptions wereRead More
AGONISTS OF PEROXISOME PROLIFERATOR-ACTIVATED RECEPTOR ALPHA AND METHODS OF USE
ABSTRACT Benzyl derivative compounds having peroxisome proliferator-activated receptor α (PPARα) agonistic activity, compositions containing such compounds, and methods of their use in enhancing PPARα activity for treating diseases and/or conditions involving inflammation and/or angiogenesis, particularly ocular diseases and/or conditions such as but not limited to retinal inflammation, retinal neovascularization, retinal vascular leakage, retinopathy of prematurity,Read More
Rheum rhaponticum Root Extract Improves Vasomotor Menopausal Symptoms and Estrogen-Regulated Targets in Ovariectomized Rat Model
ABSTRACT Ovarian insufficiency and ovariectomy are characterized by deregulated heat loss mechanisms. Unlike hormone therapy, ERr 731 (a standardized botanical extract of Siberian rhubarb Rheum rhaponticum L. high in rhaponticin) acts like a selective estrogen receptor modulator for ERβ receptors and may offer a higher degree of safety while maintaining the desired efficacy profile. InRead More

Lipoxygenase catalyzed metabolites derived from docosahexaenoic acid are promising antitumor agents against breast cancer
ABSTRACT Docosahexaenoic acid (DHA) is known to inhibit breast cancer in the rat. Here we investigated whether DHA itself or select metabolites can account for its antitumor action. We focused on metabolites derived from the lipoxygenase (LOX) pathway since we previously showed that they were superior anti-proliferating agents compared to DHA; 4-OXO-DHA was the mostRead More
A thermoresponsive hydrogel system for long-acting corticosteroid delivery into the paranasal sinuses
ABSTRACT Delivering localized treatment to the paranasal sinuses for diseases such as chronic rhinosinusitis (CRS) is particularly challenging because of the small natural openings leading from the sinuses that can be further obstructed by presence of inflammation. As such, oral steroids, topical nasal sprays or irrigation, and surgery can be utilized to treat persistent sinonasalRead More

Synthesis and evaluation of 17α-triazolyl and 9α-cyano derivatives of estradiol
ABSTRACT A variety of 17α-triazolyl and 9α-cyano derivatives of estradiol were prepared and evaluated for binding to human ERβ in both a TR-FRET assay, as well as ERβ and ERα agonism in cell-based functional assays. 9α-Cyanoestradiol (5) was nearly equipotent as estradiol as an agonist for both ERβ and ERα. The potency of the 17α-triazolylestradiolRead More
Three-dimensional liver models: state of the art and their application for hepatotoxicity evaluation
ABSTRACT While alternative methods for toxicity testing using re-constructed human skin and cornea have been written into guidelines and adopted by regulatory authorities, three-dimensional (3D) liver models are currently applied in the industrial settings for hepatotoxicity screening and prediction. These 3D liver models can recapitulate the architecture, functionality and toxicity response of the native liver,Read More
