Synthesis and biological evaluation of novel 2,4-diaminoquinazoline derivatives as SMN2 promoter activators for the potential treatment of spinal muscular atrophy

Proximal spinal muscular atrophy (SMA) is an autosomal recessive disorder characterized by death of motor neurons in the spinal cord that is caused by deletion and/or mutation of the survival motor neuron gene (SMN1). Adjacent to SMN1 are a variable number of copies of the SMN2 gene. The two genes essentially differ by a single nucleotide, which causes the majority of the RNA transcripts from SMN2 to lack exon 7. Although both SMN1 and SMN2 encode the same Smn protein amino acid sequence, the loss of SMN1 and incorrect splicing of SMN2 have the consequence that Smn protein levels are insufficient for the survival of motor neurons. The therapeutic goal of our medicinal chemistry effort was to identify small-molecule activators of the SMN2 promoter that, by up-regulating gene transcription, would produce greater quantities of full-length Smn protein. Our initial medicinal chemistry effort explored a series of C5 substituted benzyl ether based 2,4-diaminoquinazoline derivatives that were found to be potent activators of the SMN2 promoter; however, inhibition of DHFR was shown to be an off-target activity that was linked to ATP depletion. We used a structure-guided approach to overcome DHFR inhibition while retaining SMN2 promoter activation. A lead compound 11a was identified as having high potency (EC50 = 4 nM) and 2.3-fold induction of the SMN2 promoter. Compound 11a possessed desirable pharmaceutical properties, including excellent brain exposure and long brain half-life following oral dosing to mice. The piperidine compound 11a up-regulated expression of the mouse SMN gene in NSC-34 cells, a mouse motor neuron hybrid cell line. In type 1 SMA patient fibroblasts, compound 11a induced Smn in a dose-dependent manner when analyzed by immunoblotting and increased the number of intranuclear particles called gems. The compound restored gems numbers in type I SMA patient fibroblasts to levels near unaffected genetic carriers of SMA.

RORgamma antagonists and inverse agonists: a patent review

Introduction: The transcription factor RORgamma plays a critical role in the expression of pro-inflammatory cytokine interleukin IL-17 and is therefore an attractive target for the treatment of inflammatory diseases. Interest in this molecular target has been heightened by the advancement of orally and topically administered RORgamma modulators into clinical trials. Areas covered: The present review seeks to summarize published patent applications from assignee companies that have disclosed Investigational New Drug (IND) filings for small molecule RORgamma/RORgammat antagonists and inverse agonists. Expert opinion: The field of RORgamma research is extremely competitive, with the majority of companies targeting psoriasis as the primary disease indication. Vitae Pharmaceuticals is currently the most advanced, with a potential first-in-class oral RORgamma-modulator for the treatment of psoriasis. Future efforts will likely expand into potential applications of RORgamma-modulators in the lesser explored immune-related areas of rheumatoid arthritis, type 1 diabetes, lupus, and irritable bowel disorder, as well as cancer immunotherapy and castration-resistant prostate cancer.

Selective and Solvent-Free Synthesis of Isoxazole-Containing Spiro-Thiazolidinones Using TiO2-SO3H as Solid Catalyst

A solvent-free nano-titania-supported sulfonic acid [nano-TiO2-SO3H (n-TSA)] catalyzed approach has been developed for the synthesis of pharmaceutically interesting new hybrids of isoxazolyl-spiro-thiazolidinones. The key feature of present investigated three component reaction of cyclic ketones (isatin, ninhydrin and acenaphthenequinone), 3-amino-5-methyl-isoxazole and alpha-mercaptocarboxylic acids involves the synthesis of a five member ring system instead of the anticipated seven member ring system & also exploits the possibility of other likely isomers, regio and diastereoselectively. The selectivity of synthesized spiro-thiazolidinone systems was established, based on the spectroscopic outcome and single crystal X-ray analyses of representative compounds. Further, the use of a solid catalyst, n-TSA under solvent-free conditions was observed to be the best choice of reaction conditions, as it not only afforded the product in higher yields in less reaction time but in an environmentally friendly manner as well.

Gas-phase standard enthalpy of formation of 3,5-dimethyl-4-nitroisoxazole determined by semi-micro-combustion calorimetry and thermal analysis

The present paper reports the determination of the standard (p = 0.1?MPa) molar enthalpy of formation in gas phase at?T = 298.15?K of?3,5-dimethyl-4-nitroisoxazole, which was derived from the enthalpy of combustion in solid state and the sublimation enthalpy. The combustion enthalpy was derived from the respective combustion energy value, which was obtained from combustion calorimetry using a static bomb combustion calorimeter in oxygen atmosphere at?T = 298.15?K. The sublimation enthalpy was obtained at the same temperature by using thermogravimetry experiments in isothermal regime. The purity and the constant pressure heat capacity of the compound were determined by using differential scanning calorimetry, priori to carry out the combustion experiments. The value obtained of formation enthalpy of compound in gas phase presents high precision and low uncertainty.

SHU00238 Promotes Colorectal Cancer Cell Apoptosis Through miR-4701-3p and miR-4793-3p

Colorectal cancer is one of the most leading causes of death. Searching for new therapeutic targets for colorectal cancer is urgently needed. SHU00238, an isoxazole derivative, was reported to suppress colorectal tumor growth through microRNAs. But the underlying mechanisms still remain unknown. Here, we explored the mechanism of SHU00238 on colorectal cancer by RT-PCR, CCK-8, flow cytometry, mirTarBase, and GO enrichment analysis. We screened partial microRNAs regulated by SHU00238 in colorectal cancer cells. Furthermore, we identified that miR-4701-3p and miR-4793-3p can reverse the acceleration of SHU00238 on colorectal cancer cell apoptosis in HCT116 Cells. Finally, we found that SMARCA5, MBD3, VPS53, EHD4 are estimated to mediate the regulation of miR-4701-3p and miR-4793-3p on colorectal cancer cell apoptosis, which targets ATP-dependent chromatin remodeling pathway and endocytic recycling pathway. Taken together, our study reveals that SHU00238 promotes colorectal cancer cell apoptosis through miR-4701-3p and miR-4793-3p, which provide a potential drug target and therapeutic strategy for colorectal cancer.

Evaluation of the medicinal properties and possible nutrient composition of citrullus lanatus (Watermelon) seeds

Background and Objective: In countries where cultivation of Citrullu slanatus (watermelon) is on the increase, watermelon is known to have invaluable benefits. Watermelon seeds are often discarded while the fleshy fruit is eaten. This study aimed at determining the medicinal and nutritive bioactive components of Citrullus lanatus through proximate, mineral, vitamin, amino acid and phytochemical analysis. Materials and Methods: In this study, seeds of watermelon were analyzed for proximate, minerals, phytochemicals and vitamin content. The proximate analysis, minerals content, vitamins, amino acids and phytochemicals screening were performed using standard guideline of AOAC, GC-MS, AAS, HPLC and the statistical analysis was carried out using the Microsoft excel software 2010 version. Results: The proximate analysis results indicated that the watermelon seeds had moisture 48.7%, ash content 0.96%, fat 22.77%, carbohydrate 13.99% and protein content 8.9%. The amino acid profile showed the seeds were rich in phenylalanine, arginine, valine, glutamate and serine content. Vitamins A and C at 68.13 and 19.45 mg kgG1, respectively were the most abundant vitamins in the seeds. The seeds also contained appreciable mineral elements such as; Fe, Mg, Na and K with K (18.189 ppm) being the highest. The phytochemistry of the samples showed a lot of compounds with known medicinal effects. Conclusion: The present findings suggested watermelon seeds as considerable source of nutrients in the diet and may have health and economic benefits due to its vitamins, minerals and phytochemicals with high level of antioxidant activities and consequently a very useful potential nutraceutical.
