Calixto-Rodriguez, M. published the artcileX-ray diffraction and compositional studies of AgInS₂ thin films obtained by spray pyrolysis, Name: 1,1-Dimethylthiourea, the publication is Journal of Materials Science (2008), 43(21), 6848-6852, database is CAplus.

Silver indium sulfide (AgInS₂) thin films have been prepared by the spray pyrolysis technique using silver acetate, indium acetate, and N,N-dimethylthiourea as precursor compounds Depending on the film preparation conditions, AgInS₂ thin films are obtained which could be candidates to be used in photovoltaic devices. X-ray diffraction and energy dispersive spectroscopy compositional studies were done on films formed at different substrate temperatures (T_s) and Ag:In:S ratios in the starting solutions When Ag:In:S ratios are 1:1:1, 1:0.25:2, and 1:1:2, x-ray diffraction patterns of the thin films indicated that the crystallog. structure is mainly chalcopyrite AgInS₂. An addnl. phase, acanthite Ag₂S, appeared when the depositions where done at low T_s. Energy dispersive spectroscopy anal. showed that AgInS₂ films near stoichiometric composition were obtained by using an at. ratio of Ag:In:S = 1:1:2 in the starting solution and T_s = 400¡ã.

Zhang, K. M. published the artcileROS Produced via BsRBOHD Plays an Important Role in Low Temperature-Induced Anthocyanin Biosynthesis in Begonia semperflorens, Recommanded Product: 1,1-Dimethylthiourea, the publication is Russian Journal of Plant Physiology (2020), 67(2), 250-258, database is CAplus.

Low temperature (LT) is an important elicitor that triggers anthocyanin biosynthesis. To investigate whether the reactive oxygen species (ROS) produced via RBOH are involved in this process, we analyzed the function and mechanism of ROS produced via RBOH during LT-induced anthocyanin biosynthesis in Begonia semperflorens Link & Otto. The results showed that BsRBOHD transcription was upregulated in LT-grown seedlings at the 3rd hour, which was followed by the upregulation of anthocyanin-biosynthesis genes at the 5-9th hour, leading to anthocyanin accumulation on the 2nd day. The LT-induced increases in ROS production, BsRBOHD and anthocyanin-biosynthesis gene transcription, and anthocyanin content were abolished by the pre-treatment of seedlings with DPI [an inhibitor of nicotinamide adenine nucleoside phosphorylase (NADPH) oxidase or DMTU (a H₂O₂ scavenger)], but were promoted by pre-treatment with NADPH (a substrate of NADPH oxidase). Changes in the chlorophyll fluorescence parameters showed that pre-treatment of DPI or DMTU alleviated the LT-induced decrease in the seedling chlorophyll content and a/b ratio, which subsequently alleviated the LT-induced decreases in the ABS/CSm, TRo/CSm, RC/CSm, ETo/CSm and REo/CSm values. In contrast, NAPDH pre-treatment intensified these changes. Therefore, we suggest that ROS produced via BsRBOHD may be involved in the LT-induced anthocyanin biosynthesis by strengthening the overaccumulation of ROS produced by the overexcitation of PSII reaction centers and overflux from [Formula Omitted] to NADP⁺ in B. semperflorens.

Huang, Tzou-Chi published the artcileDiallyl disulphide, but not diallyl sulphide, increases leucocyte function-associated antigen-1 expression and cellular adhesion in monocytes, Quality Control of 6972-05-0, the publication is Food Chemistry (2010), 120(1), 113-120, database is CAplus.

A steam distillation process at pH 9 was conducted to prepare garlic oil for food supplement. A garlic oil predominant in bioactive diallyl monosulfide (8.9%), diallyl disulfide (56.9%) diallyl trisulfide (7.6%) and diallyl tetrasulfide (2.6%) was obtained from peeled garlic cloves. The adhesion mol. leukocyte function-associated antigen-1 (LFA-1) mediates leukocyte adhesion and migration during immune responses. In this study, we investigated the effects of diallyl sulfide (DAS) and diallyl disulfide (DADS) on LFA-1 expression, cell adhesion and migration in the U937 and peritoneal macrophages from mice. After treatment, DADS, but not DAS, elevated the expression of LFA-1 in a dose- and time-dependent manner in U937 cells and peritoneal macrophages. Moreover, LFA-1 and intracellular adhesion mol.-1 (ICAM-1)-mediated adhesion also was increased by DADS in a dose- and time-dependent manner. After DADS treatment, LFA-1 clustering also increased on U937 surface. In contrast, there was no significant difference in migration of U937 cells between DADS treatment and no treatment. This study indicates the DADS, but not DAS, regulates immune responses by modulating LFA-1 expression, clustering and LFA-1-mediated adhesion in monocytes, evidences that DADS acts as an immune regulator of adhesion mols. during immune responses.

Jones, Peter G. published the artcileMethylthioureas and their morpholine and dioxane adducts; hydrogen-bonding patterns, Recommanded Product: 1,1-Dimethylthiourea, the publication is Acta Crystallographica, Section B: Structural Science, Crystal Engineering and Materials (2013), 69(4), 405-413, database is CAplus and MEDLINE.

The authors have redetermined the known structures of (i) methylthiourea (MTU) and (ii) 1,1-dimethylthiourea (1,1-DMTU), and studied the structure of 1,3-dimethylthiourea (1,3-DMTU), which was however severely disordered. The authors report the structures of crystalline adducts of (iii) MTU with morpholine (1:1), (iv) 1,1-DMTU with 1,4-dioxane (2:1) and (v) 1,3-DMTU with 1,4-dioxane (2:1). Finally, (vi) the authors determined the structure of tetramethylthiourea (TetMTU). (i) In both independent mols. of MTU, the Me group is trans to the C=S group across the C-N bond. The two mols. are connected to form an R₂²(8) dimer by mutual N-H¡¤¡¤¡¤S=C interactions. The packing involves six N-H¡¤¡¤¡¤S=C interactions and is three-dimensional. (ii) The packing of the MTU-morpholine adduct is a layer structure, within which both mols. form linear aggregates parallel to the b axis. (iii) The packing of 1,1-DMTU involves N-H¡¤¡¤¡¤S=C H bonds forming a corrugated layer structure. (iv) In the 2:1 adduct between 1,1-DMTU and 1,4-dioxane, the DMTU mol. occupies a general position whereas the dioxane mol. lies across an inversion center. The crystal packing involves chains of alternating 1,1-DMTU R₂²(8) dimers and dioxanes, both across inversion centers. (v) In the 2:1 adduct between 1,3-DMTU and dioxane, the 1,3-DMTU mol. occupies a general position, while the dioxane mol. lies across an inversion center. One Me group of the DMTU is trans and one cis to the S across the corresponding C-N bond. The mols. form chains of alternating 1,3-DMTU R₂²(8) dimers and dioxanes, both across inversion centers. Crystals of the 2:1 adduct between 1,3-DMTU and morpholine were also obtained, and were isotypic with the dioxane adduct. The morpholine mol. is disordered across the inversion center. (vi) The mol. of TetMTU displays crystallog. 2-fold symmetry. Significant distortions reflect the steric pressure between Me groups trans to S. The packing of TetMTU involves only a weak H bond, C-H_methyl¡¤¡¤¡¤S, which connects the mols. to form layers. Crystallog. data are given.

Zhang, Zeyu published the artcileExplant disinfection with chlorine dioxide promotes adventitious shoot organogenesis in Crassula portulacea via the regulation of reactive oxygen species and related gene expression, SDS of cas: 6972-05-0, the publication is Plant Cell, Tissue and Organ Culture (2021), 146(3), 531-540, database is CAplus.

Abiotic oxidative stress may activate plant organ development and growth. However, this effect is rarely reported for in vitro tissue culture. We report enhanced adventitious shoot formation in Crassula portulacea through the disinfection of explants with an environmentally safe oxidant chlorine dioxide (CD) and explore the involvement of reactive oxygen species (ROS) accumulation and the expression of organogenesis-associated genes. A concentration of 0.62-1.24 mM CD was effective at disinfecting C. portulacea explants within 15 min. Interestingly, the disinfection of explants with CD significantly promoted the formation of adventitious shoots, resulting in a 3-5-fold enhancement of the number of adventitious shoots when compared with the disinfection of explants using 0.1% mercuric chloride. Superoxide anions, hydrogen peroxide and superoxide dismutase increased in the CD treatment, while the enhancements were significantly suppressed when N,N’-dimethylthiourea (DMTU) was applied, indicating that CD-promoted adventitious shoot formation correlates with ROS accumulation. The expression of CpWUS, CpCYCB1 and CpCUC1 was upregulated in explants disinfected with CD, while the application of DMTU significantly suppressed their expression, consistent with adventitious shoot development. These findings present new insights into understanding the physiol. and mol. mechanisms of plant tissue culture and providing an efficient micropropagation protocol for C. portulacea.

AM1 was more than MNDO, or PM3 for calculating rotational barriers of compounds containing a RRN-CX-R linkage (amides, thioamides, ureas and thioureas). The barriers calculated with AM1 must be corrected using the equation ¦¤G_liquid^? = 1.6¦¤H_(AM1)^? + 4.5 kcal mol^-1 to obtain the best coincidence with exptl. values. Another equation, ¦¤H_ab?_initio^? = 1.35¦¤H_(AM1)^? + 2.05 kcal mol^-1 reproduces recent ab initio data well.
