Kim, Hyeon-Young; Kim, Tae Rim; Kim, Sung-Hwan; Kim, In-Hyeon; Ko, Youngho; Yun, Sungil; Lee, In-Chul; Park, Han-Oh; Kim, Jong-Choon published the artcile< Genotoxicity evaluation of self-assembled-micelle inhibitory RNA-targeting amphiregulin (SAMiRNA-AREG), a novel siRNA nanoparticle for the treatment of fibrotic disease>, HPLC of Formula: 6055-19-2, the main research area is amphiregulin SAMiRNA targeting nanoparticle fibrotic disease treatment genotoxicity; GLP study; Self-assembled-micelle interfering RNA nanoparticle; amphiregulin; genotoxicity; safety evaluation.

The self-assembled-micelle inhibitory RNA-targeting amphiregulin (SAMiRNA-AREG) is a novel small-interfering RNA (siRNA) nanoparticle that is used for treatment of pulmonary fibrosis. We investigated the potential genotoxicity of SAMiRNA-AREG based on the guidelines published by the Organization for Economic Cooperation and Development. In the bacterial reverse mutation assay (Ames test), SAMiRNA-AREG did not induce mutations in Salmonella typhimurium TA100, TA1535, TA98, and TA1537 and Escherichia coli WP2uvrA at concentrations of up to 3000μg/plate with or without metabolic activation. The SAMiRNA-AREG (concentrations up to 500μg/mL) did not induce chromosomal aberrations in cultured Chinese hamster lung cells with or without metabolic activation. In the in vivo mouse bone marrow micronucleus assay, the SAMiRNA-AREG (concentrations up to 300 mg/kg body weight) did not affect the proportions of polychromatic erythrocytes and total erythrocytes, nor did it increase the number of micronucleated polychromatic erythrocytes in ICR mice. Collectively, these results suggest that SAMiRNA-AREG is safe with regard to genotoxicity such as mutagenesis or clastogenesis under the present exptl. conditions. These results might support the safety of SAMiRNA-AREG as a potential therapeutic agent for pharmaceutical development.

Park, Seojeong; Hong, Eunji; Kwak, Soo Yeon; Jun, Kyu-Yeon; Lee, Eung-Seok; Kwon, Youngjoo; Na, Younghwa published the artcile< Synthesis and biological evaluation of C1-O-substituted-3-(3-butylamino-2-hydroxy-propoxy)-xanthen-9-one as topoisomerase IIα catalytic inhibitors>, COA of Formula: C8H8BrCl, the main research area is xanthone preparation topoisomerase IIa catalytic inhibitory anticancer activity; Anticancer agents; C1-alkyl and arylalkyl substituted xanthones; Topoisomerase IIα catalytic inhibitor.

Topoisomerase II poison blocks the transitorily generated DNA double-strand breaks (DSBs) from religation, thereby causes severe DNA damage and gene toxicity. While topoisomerase II catalytic inhibitor does not form cleavable DNA-enzyme complex because its function attributes to inhibition of the catalytic steps of the enzyme such as before generating DNA DSBs or in the last step of the catalytic cycle after religation. It has been reported that the stabilizing effect of etoposide on transient cleavable DNA-topoisomerase IIβ complex attributes to its secondary malignancy. Therefore, topoisomerase IIα has been considered as more attractive target than topoisomerase IIβ for the development of chemotherapeutic agents. In the previous work, we reported compounds as novel topoisomerase IIα catalytic inhibitors targeting for ATP binding site of human topoisomerase IIα ATP-binding domain. As a continuous work, we have designed and synthesized 43 compounds of C1-O-alkyl and arylalkyl substituted compounds with or without methoxy group on ring A. In the topoisomerase IIα inhibitory test, among the tested C1-O-4-chlorophenethyl substituted compounds I (R1 = H, OMe) were more active than others, and compound I (R1 = H) showed strongest topoisomerase IIα inhibitory activity with 94.4% and 23.0% inhibition, resp., at 100 and 20 μM. Compounds I (R1 = H, OMe) have also showed much enhanced cytotoxic activity against T47D cells; IC50 (μM): 0.63 ± 0.01 and 0.19 ± 0.02, resp., which are stronger than reference drugs. Band depletion assay and cleavage complex assay results showed compounds I (R1 = H, OMe) were potential topoisomerase IIα catalytic inhibitor with low DNA damage.

Amperayani, Karteek Rao; Parimi, Uma Devi published the artcile< Effect of silk strength by dietary supplementation of silk worm with 1,3,4-thiadiazoles, in silico and in vitro Bombyx mori DNA binding studies>, Product Details of C8H6ClN3S, the main research area is Bombyx silk strength feeding thiadiazole DNA binding.

In silico and in vitro DNA binding studies were carried out on silk worm DNA to determine the efficiency of 1,3,4-thiadiazoles (Th1-9) on Bombyx mori larvae during their 5th instar larval stage to increase the tensile strength, quality and quantity of biopolymer silk. These compounds were synthesized using ultrasonication method and supplied in ultra-dose as food supplement along with mulberry leaves to Bombyx mori and recorded the growth and other parameters of silkworm, cocoon parameters and mech. testing of silk filament. Tensile Strength, elongation and quantity of the silk was higher in larvae fed with synthesized compound in comparison with control larvae. This increase in strength and quality was due to the strong binding interactions of thiadiazoles moiety with silk worm DNA which was confirmed by higher binding energy values showed in In silco studies and DNA binding assay results.

Vasquez, Marie Z. published the artcile< Combining the in vivo comet and micronucleus assays: a practical approach to genotoxicity testing and data interpretation>, Electric Literature of 6055-19-2, the main research area is Comet assay micronucleus genotoxicity safety.

Despite regulatory directives requiring the reduction of animal use in safety testing, recent modifications to genotoxicity testing guidelines now propose the use of two in vivo genotoxicity assays as a follow-up to an in vitro pos. (International Conference on Harmonization Consensus Draft Guidance S2[R1] released March, 2008). To address both goals, the in vivo comet and micronucleus (MN) assays can be successfully combined into one informative study. Combining these two assays with such differences in sensitivity, endpoints measured and the type of data generated significantly improves upon the current standard capabilities for detecting genotoxicity without requiring addnl. animals. But to take full advantage of the benefits of incorporating the comet assay in safety testing, these same differences must be recognized and considered. Developed from over 15 years experience using the in vivo comet and MN assays in genotoxicity testing of chems. and pharmaceuticals, this paper presents guidelines for the appropriate exptl. design, dose selection and data interpretation for combined in vivo comet/MN assay studies. To illustrate the approach, data from combined assay studies are presented and discussed.

Zhu, Gang; Wang, Fei; Liu, Wenjie; Gong, Xinjian; Geng, Pengfei; Gao, Zhenwei; Wang, Yinghan published the artcile< Synthesis of photosensitive polyimide for liquid crystal alignment under non-polarized UV ageing lamp irradiation and a study on the possible mechanism of alignment>, Recommanded Product: (E)-Cinnamoyl chloride, the main research area is photosensitive polyimide liquid crystal UV lamp irradiation alignment.

A new photosensitive polyimide (PI) was successfully synthesized via esterification of PI containing hydroxyl groups with cinnamoyl chloride (CL). The cinnamate (CA) group contents of the PI was up to 90%. The PI films could induce uniform parallel alignment of liquid crystal (LC) mols. after the non-polarized UV ageing lamp exposure, which reduce the cost significantly compared with polarized UV light equipment. In addition, the PI exhibited good thermal stability. Meanwhile, the possible mechanism of PI alignment films induced by NPUVL was discussed in some detail.

Ju, Changha; Kang, Shinwoo; Kim, Taehyung; Park, Chanhyuk; Kang, Hyo published the artcile< Vertical liquid crystal alignment of comb-like alkyl hydroxybenzoate-substituted polystyrene>, Reference of 1592-20-7, the main research area is alkyl hydroxybenzoate polystyrene vertical liquid crystal alignment.

We investigated the liquid crystal (LC) alignment behaviors of Bu hydroxybenzoate-substituted polystyrene (PBHB#; # = 20, 40, 60, 80, and 100, where # indicates the molar fraction of Bu hydroxybenzoate in the side chain), Me hydroxybenzoate-substituted polystyrene (PMHB100), and Et hydroxybenzoate-substituted polystyrene (PEHB100). Generally, LC cells made employing polymer films having longer alkyl groups in the side chain show vertical LC alignment. For instance, a LC cell fabricated with the PMHB100 film showed random planar LC alignment, while the LC cells made from the PEHB100 and PBHB100 films exhibited vertical LC alignment. Moreover, LC cells prepared from a polymer film having a higher molar content of Bu hydroxybenzoate in the side chain exhibited vertical LC alignment. The observed vertical LC alignment behaviors are closely related to the surface energy of these polymer films. For instance, vertical LC alignment was observed when the surface energy of the polymer film was less than ∼43.86 mJ/m2, which could result from the nonpolar alkyl groups of the alkyl hydroxybenzoate moiety. The LC cell prepared from PBHB100 as the LC alignment layer showed good electro-optical characteristics such as voltage holding ratio, residual DC voltage, and alignment stability at 200°C.
