Phototheranostics, which combines deep tissue imaging and phototherapy [photodynamic therapy (PDT) and/or photothermal therapy (PTT)] via light irradiation, is a promising strategy to treat tumors. Near-IR (NIR) cyanine dyes are researched as potential phototheranostics reagents for their excellent photophys. properties. However, the low singlet oxygen generation efficiency of cyanine dyes often leads to inadequate therapeutic efficacy for tumors. Herein, we modified an indocyanine green derivative Cy7 with heavy atom iodine to form a novel NIR dye CyI to improve the reactive oxygen species (ROS) production and heat generation while, at the same time, maintain their fluorescence characteristics for in vivo noninvasive imaging. More importantly, in vitro and in vivo therapeutic results illustrated that CyI could quickly and simultaneously generate enhanced ROS and heat to induce more cancer cell apoptosis and higher inhibition rates in deep HepG2 tumors than other noniodinated NIR dyes upon NIR irradiation Besides, low toxicity of the resulted iodinated NIR dyes was confirmed by in vivo biodistribution and acute toxicity. Results indicate that this low toxic NIR dye could be an ideal phototheranostics agent for deep tumor treatments. Our study presents a novel approach to achieve the fast-synergistic PDT/PTT treatment in deep tissues.

Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Catalytic Asymmetric Homologation of Ketones with α-Alkyl α-Diazo Esters.

The homologation of ketones with diazo compounds was a useful strategy to synthesize one-carbon chain-extended acyclic such as PhC(O)CMeCO2MeR [R = allyl, Bn, CH2(2-naphthyl), etc.] or ring-expanded cyclic ketones e.g., I. However, the asym. homologation of acyclic ketones with α-diazo esters remains a challenge due to the lower reactivity and complicated selectivity. Herein, the enantioselective catalytic homologation of acetophenone and related derivatives with α-alkyl α-diazo esters was reported utilizing a chiral scandium(III) N,N’-dioxide as the Lewis acid catalyst. This reaction supplies a highly chemo-, regio-, and enantioselective pathway for the synthesis of optically active β-keto esters with an all-carbon quaternary center through highly selective alkyl-group migration of the ketones. Moreover, the ring expansion of cyclic ketones was accomplished under slightly modified conditions, affording a series of enantioenriched cyclic β-keto esters. D. functional theory calculations was carried out to elucidate the reaction pathway and possible working models that could explain the observed regio- and enantioselectivity.

Author is Pantelic, Nebojsa D.; Bozic, Bojan; Zmejkovski, Bojana B.; Banjac, Nebojsa R.; Dojcinovic, Biljana; Wessjohann, Ludger A.; Kaluderovic, Goran N..

The synthesis of novel triphenyltin(IV) compounds, Ph3SnLn (n = 1-3), with oxaprozin (3-(4,5-diphenyloxazol-2-yl)propanoic acid), HL1, and the new propanoic acid derivatives 3-(4,5-bis(4-methoxylphenyl)oxazol-2-yl)propanoic acid, HL2, and 3-(2,5-dioxo-4,4-diphenylimidazolidin-1-yl)propanoic acid, HL3, has been performed. The ligands represent com. drugs or their derivatives and the tin complexes have been characterized by standard anal. methods. The in vitro antiproliferative activity of both ligands and organotin(IV) compounds has been evaluated on the following tumor cell lines: human prostate cancer (PC-3), human colorectal adenocarcinoma (HT-29), breast cancer (MCF-7), and hepatocellular cancer (HepG2), as well as on normal mouse embryonic fibroblast cells (NIH3T3) with the aid of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-12 diphenyltetrazolium bromide) and CV (crystal violet) assays. Contrary to the inactive ligand precursors, all organotin(IV) carboxylates showed very good activity with IC50 values ranging from 0.100 to 0.758 μM. According to the CV assay (IC50 = 0.218 ± 0.025 μM), complex Ph3SnL1 demonstrated the highest cytotoxicity against the caspase 3 deficient MCF-7 cell line. Inductively coupled plasma mass spectrometry (ICP-MS) anal. indicated a two-fold lower concentration of tin in MCF-7 cells in comparison to platinum. To investigate the mechanism of action of the compound Ph3SnL1 on MCF-7 cells, morphol., autophagy and cell cycle anal., as well as the activation of caspase and ROS/RNS and NO production, has been performed. Results suggest that Ph3SnL1 induces caspase-independent apoptosis in MCF-7 cells.

Quality Control of Ethylenediaminetetraaceticacidferricsodiumsalttrihydrate. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Ethylenediaminetetraaceticacidferricsodiumsalttrihydrate, is researched, Molecular C10H18FeN2NaO11, CAS is 2489531-02-2, about Stability evaluation of iron and vitamin A during processing and storage of fortified pasta. Author is Sharma, N.; Sharma, S.; Singh, B.; Kaur, G..

Pasta holds greater potential for improving the nutritional status of the population and its fortification with micronutrients like iron and vitamin A could be an effective strategy to provide the essential nutrients in the diet. This study quantified the losses of two different micronutrients (iron and vitamin A) in fortified pasta postprocessing and during storage for 4 mo. Chem. salts of iron, namely, ferric sodium ethylene diamine tetra-acetic acid (NaFeEDTA) and ferrous sulfate (FeSO4), were added to pasta formulation at 4,5,6 mg/100g and 6,7,8 mg/100g resp., whereas for vitamin A, retinyl acetate (RA) was added at 700, 800 and 900μg/100g. After processing, the prepared pasta with both iron salts showed retention of 94-95% for iron and 90-92% of vitamin A activity. Iron and vitamin A-fortified pasta with maximum retention during processing and exhibiting optimum color attributes and sensory score were stored alone and in combination (NaFeEDTA and RA) at 25 and 40°C in laminates (aluminum laminates) and polypropylene packets for a period of 4 mo and evaluated for changes in their iron and vitamin A contents. An overall retention of 93-95% of the iron and 56-62% of vitamin A was observed after 4 mo considering losses during processing and storage. Among the two packaging materials used, laminates retained more of iron and vitamin A activity than polypropylene. No difference in retention rates was observed for iron and vitamin A when fortified alone or in combination.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 254905-58-3, is researched, Molecular C13H24N2O3, about Conformationally restrained carbamoylcholine homologues. Synthesis, pharmacology at neuronal nicotinic acetylcholine receptors and biostructural considerations, the main research direction is carbamoylcholine homolog pharmacol neuron nicotinic receptor ligand; Acetylcholine; Agonist; Conformational restriction; Docking; Nicotinic acetylcholine receptor.COA of Formula: C13H24N2O3.

Exploration of small selective ligands for the nicotinic acetylcholine receptors (nAChRs) based on acetylcholine (ACh) has led to the development of potent agonists with clear preference for the α4β2 nAChR, the most prevalent nAChR subtype in the central nervous system. In this work the authors present the continuation of these efforts aimed at increasing this subtype selectivity by introduction of conformational restriction in the carbamoylcholine homolog, 3-(dimethylaminobutyl) dimethylcarbamate (DMABC). The results highlight the importance of the N-carbamoyl substitution in α4β2-subtype selectivity. Moreover, the authors have confirmed the non-linear conformation of DMABC bound to nAChRs suggested by recent crystal structures of the compound in complex with the Lymnaea stagnalis ACh binding protein.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Design, Synthesis, and Activity Evaluation of Novel Acyclic Nucleosides as Potential Anticancer Agents In Vitro and In Vivo, the main research direction is colon cancer drug discovery anticancer acyclic nucleoside synthesis chloropurinyldodecanol; structure activity antitumor acyclic nucleoside synthesis human apoptosis.Synthetic Route of C4H7BrO2.

In the present work, 103 novel acyclic nucleosides were designed, synthesized, and evaluated for their anticancer activities in vitro and in vivo. The structure-activity relationship (SAR) studies revealed that most target compounds inhibited the growth of colon cancer cells in vitro, of which (chloro-9H-purinyl)dodecanol I exhibited the most potent effect against the HCT-116 and SW480 cells with IC50 values of 0.89 and 1.15μM, resp. Furthermore, all of the (R)-configured acyclic nucleoside derivatives displayed more potent anticancer activity compared to their (S)-counterparts. Mechanistic studies revealed that compound I triggered apoptosis in the cancer cell lines via depolarization of the mitochondrial membrane and effectively inhibited colony formation. Importantly, I inhibited the growth of the SW480 xenograft in a mouse model with low systemic toxicity. These results indicated that acyclic nucleoside compounds are viable as potent and effective anticancer agents, and I may serve as a promising lead compound that merits further attention in future anticancer drug discovery.
