An oxidant-free Rh(III)-catalyzed direct amidation of alkyl dithianes I (R¹ = Me, Ph, PhCH₂, MeO₂C, etc., R² = Me; R¹R² = CH₂CH₂NBocCH₂CH₂) via C(sp³)-H bond activation utilizing diverse and robust dioxazolone reagents II (R³ = t-BuCH₂, cyclopropyl, n-undecyl, Ph, PhCH₂, 2-furyl, etc.) is reported. The reaction hinges on use of a Cp*Rh(III) complex in combination with an essential amino-carboxylate additive to generate usefully protected 1,3-aminoaldehyde derivatives III. The scalability of the reaction was demonstrated as was a series of downstream product functionalizations, including dithiane deprotection, anion alkylation and reductive desulfurization, highlighting the general applicability of this transformation in the synthesis of novel scaffolds and building blocks. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0Related Products of 6834-42-0).

Species and Life-Stage Sensitivity of Chinese Rare Minnow (Gobiocypris rarus) to Chemical Exposure: A Critical Review was written by Bai, Yunfei;Lian, Deru;Su, Tenghui;Wang, Yolina Yu Lin;Zhang, Dainan;Wang, Zhen;Gimeno, Sylvia;You, Jing. And the article was included in Environmental Toxicology and Chemistry in 2021.Formula: C13H9Cl3N2O This article mentions the following:

Chem. production and consumption in Asia are increasing at an unprecedented rate, calling for regulations on chem. management. Under the New Chem. Substance Notification in China, information on ecotoxicol. effects of chems. is mandatory for the simplified registration of chems. with the requirement that one ecotoxicol. test is conducted locally. It is now mandatory to use the native fish species Chinese rare minnow (Gobiocypris rarus). However, its chem. sensitivity compared to that of fathead minnow (Pimephales promelas) or zebrafish (Danio rerio) is still unclear. We performed a holistic literature review on toxicity data with G. rarus from 1997 to 2020. Species sensitivity among G. rarus, P. promelas, and D. rerio and life-stage sensitivity of G. rarus were systematically investigated for various chems. using both chem. ratio distribution and probabilistic chem. toxicity distribution approaches. Comparatively, the Chinese native fish species G. rarus was more sensitive than D. rerio, particularly to metals. Juvenile and adult G. rarus were more sensitive than its larvae and embryos. The observed lower sensitivity of G. rarus embryo was likely due to the thick embryonic chorion, discrepant methods of collecting embryos, and the paucity of toxicity data, implying the necessity to standardize G. rarus embryo tests and validate the sensitivity with various types of chems. This unique review allows us to conclude that G. rarus studies could be used in worldwide registrations and that further investigations are needed to use G. rarus embryos as alternatives to the fish test. Environ Toxicol Chem 2021;00:1-14. 2021 SETAC In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Formula: C13H9Cl3N2O).

1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Formula: C13H9Cl3N2O

Effect of endocrine disrupting chemicals on vitronectin-receptor (integrin alphaVbeta3)-mediated cell adhesion of human umbilical vein endothelial cells was written by Kenda, Masa;Pecar Fonovic, Ursa;Kos, Janko;Sollner Dolenc, Marija. And the article was included in Toxicology In Vitro in 2022.Synthetic Route of C13H9Cl3N2O This article mentions the following:

Endocrine disrupting chems. (EDCs) are associated with cancer development and progression due to their promotion of increased cell invasiveness and metastasis formation. However, the effects of EDCs on cell adhesion mediated through integrins have not been well studied to date. Their actions are implicated by binding sites for hormones on the vitronectin receptor (VTNR; or integrin αvβ3), which is involved in tumor angiogenesis and metastasis. VTNR-expressing human umbilical vein endothelial cells (HUVECs) were used to determine the effects of EDCs and endogenous hormones on cell adhesion to vitronectin-coated surfaces, and on VTNR activation. Cell adhesion was significantly increased for bisphenol A, triclocarban, and triclosan (10, 100 nM; p < 0.05), with similar trends for bisphenols AF and S (10, 100 nM; p > 0.05). No changes in cell adhesion were seen for 5α-dihydrotestosterone, 17β-estradiol, triiodothyronine, imatinib and paroxetine. These data indicate that EDC-mediated increases in HUVEC adhesion to vitronectin are not mediated through androgenic, estrogenic, or thyroid activities, nor through activation of VTNR. Although these effects of EDCs on HUVEC adhesion require further investigation of the underlying mechanism(s) of action to define their biol. relevance, the low-dose effects and nonmonotonic responses revealed here define the need for further investigation of these EDCs. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Synthetic Route of C13H9Cl3N2O).

1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Synthetic Route of C13H9Cl3N2O

Discovery of novel tertiary amide derivatives as NEDDylation pathway activators to inhibit the tumor progression in vitro and in vivo was written by Fu, Dong-Jun;Song, Jian;Zhu, Ting;Pang, Xiao-Jing;Wang, Sheng-Hui;Zhang, Yan-Bing;Wu, Bo-Wen;Wang, Jun-Wei;Zi, Xiaolin;Zhang, Sai-Yang;Liu, Hong-Min. And the article was included in European Journal of Medicinal Chemistry in 2020.Computed Properties of C8H9Cl This article mentions the following:

NEDDylation pathway regulates multiple physiol. process, unlike inhibitors, NEDDylation activators are rarely studied. Novel amide derivatives were synthesized and evaluated for antiproliferative activity against MGC803, MCF-7 and PC-3 cells. Among them, VII-31 displayed the most potent activity with an IC₅₀ value of 94 nmol/L against MGC803 cells. Cellular mechanisms elucidated that VII-31 inhibited the cell viability, arrested cell cycle at G2/M phase and induced apoptosis via intrinsic and extrinsic pathways against MGC803 cells. In addition, VII-31 activated NAE1-Ubc12-Cullin1 NEDDylation via interacting with NAE1 directly. Furthermore, the activation of NEDDylation resulted in the degradation of inhibitor of apoptosis proteins (IAPs). Importantly, VII-31 inhibited tumor growth in xenograft models in vivo without the apparent toxicity. In summary, it is the first time to reveal that VII-31 deserves consideration for cancer therapy as a NEDDylation activator. In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9Computed Properties of C8H9Cl).

1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Computed Properties of C8H9Cl

17β-HSD2 inhibitors for the treatment of osteoporosis: Identification of a promising scaffold was written by Wetzel, Marie;Marchais-Oberwinkler, Sandrine;Hartmann, Rolf W.. And the article was included in Bioorganic & Medicinal Chemistry in 2011.COA of Formula: C9H9ClO2 This article mentions the following:

17β-Hydroxysteroid dehydrogenase type 2 (17β-HSD2) catalyzes the conversion of active 17β-hydroxysteroids into the less active 17-ketosteroids thereby controlling the availability of biol. active estrogens (E2) and androgens (T) in the tissues. The skeletal disease osteoporosis occurs mainly in post-menopausal women and in elderly men when the levels of estrogens and androgens, resp., decrease. Since 17β-HSD2 is present in osteoblasts, inhibition of this enzyme may provide a new and promising approach to prevent the onset of osteoporosis, keeping a certain level in estrogens and androgens in bone cells of ageing people. Hydroxynaphthyl, hydroxyphenyl and hydroxymethylphenyl-substituted moieties were synthesized as mimetics of the steroidal substrate. Compound 8 has been identified as promising scaffold for 17β-HSD2 inhibitors displaying high activity and good selectivity toward 17β-HSD1, ERα and ERβ. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0COA of Formula: C9H9ClO2).

2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).COA of Formula: C9H9ClO2

And the article was included in Journal of Photochemistry and Photobiology, A: Chemistry in 2022.Related Products of 61-73-4 This article mentions the following:

In this study, the crystallized and amorphous Ta₂O₅ nanospheres were successfully synthesized by a simple alc.-thermal reaction. The particle sizes of amorphous Ta₂O₅ nanospheres were controlled by adjusting the PVP amount in the synthetic system. The removal abilities of the Ta₂O₅ towards organic dyes were assessed by measuring the adsorption and the photocatalytic degradation performance towards methylene blue (MB) under dark condition and simulated solar light irradiation, resp. The results indicate that the amorphous Ta₂O₅ prepared with 1:5 PVP (a-Ta₂O₅ 5PVP) exhibited extremely high adsorption abilities and photocatalytic degradation performances, compared to the crystallized and other amorphous Ta₂O₅ nanospheres. The excellent MB removal ability of a-Ta₂O₅ 5PVP can be attributed to high sp. surface area, extra O vacancies, enhanced visible light absorption, more photo-generated electrons and low charge transfer resistance. This study may shed light on a simple but low-cost preparation strategy for amorphous Ta₂O₅ nanospheres suitable for the future practical application on wastewater treatment and provide deep insights on the underlying reasons for the high removal performance to organic dyes.
