Design, synthesis, and anticancer evaluation of some novel thiourea, carbamimidothioic acid, oxazole, oxazolidine, and 2-amino-1-phenylpropyl-2-chloroacetate derived from L-norephedrine

A novel series of thiourea, carbamimidothioic acid, 4, 5-dihydrooxazole-2-thiol, oxazolidine-2thine, and 2-amino-1-phenylpropyl-2-chloroacetate derivatives was designed and synthesized using 2-amino-1-phenylpropan-1-ol (L-norephedrine) as a strategic starting material. The structures of the newly synthesized compounds were established by elemental analyses, IR, and H-1 NMR and C-13 NMR spectral data. The compounds were evaluated for their in vitro anticancer activity against various cancer cell lines. The corresponding acetamide, carbamimidothioic acid, and 2-2-amino-1-phenylpropyl-2-chloroacetate derivatives showed almost the same activity as the standard drug doxorubicin against human breast cancer cell line (MCF-7). Also, the acetamide and 2-thioxoimidazolidin-4-one derivatives exhibited higher activity than the reference drug doxorubicin against human colon cancer cell line (HCT 116).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 16251-45-9, in my other articles.

Solvent and Base in One: Tetra-n-butylammonium Acetate as a Multi-Purpose Ionic Liquid Medium for Ru-Catalyzed Directed Mono- and Di-o-C-H Arylation Reactions

Ru-catalyzed directed o-C-H arylation reactions of 2-phenylpyridine, N-phenylpyrazole, acetophenone N-(p-methoxyphenyl)imine, and 2-phenyloxazoline proceed in good to excellent yields with a number of functionalized aryl and heteroaryl bromides in neat Bu4NOAc at 120 degrees C. The acetate ion acts as the base and the relatively low melting point Bu4N salts (a mixture of acetate and bromide) behave as an ionic liquid. Arylation reactions of 2-phenyloxazoline proceed with concomitant oxazolidine cleavage to give 2-(N-acetylamino)ethyl benzoates promoted by side product CH3COOH. The dual-purpose ionic liquid medium is compatible with both ligandless Ru for di-arylation (optimal pre-catalyst: RuCl3xH2O) and Ru-phosphane (optimal pre-catalyst: [RuCl2(p-cymene)](2)/P(p-Tol)(3) 1:4) catalysts (1-5 mol-%) for selective mono-arylation.

Synthetic Route of 6704-31-0, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 6704-31-0.

Fe-catalyzed synthesis of substituted N-aryl oxazolidines

A novel iron-catalyzed synthesis of substituted N-aryl oxazolidines was developed via C-N bond formation and methylenation. The reaction of aryl hydroxylamines with allyl alcohols, in the presence of formaldehyde or its equivalents, afforded variety of oxazolidine heterocycles in very good yields. This catalytic method is most effective for para-substituted aryl hydroxylamines and 3-methyl allyl alcohols. Furthermore, acid catalyzed demethylenation of oxazolidines allowed access to N-aryl amino alcohols in good yields.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 34052-90-9 is helpful to your research. Product Details of 34052-90-9.

Microwave-assisted and conventional synthesis of novel antimicrobial 1,2,4-triazole derivatives containing nalidixic acid skeleton

Carbothioamides 4a,b, obtained from nalidixic acid, were converted to the corresponding 1,3-thiazolidine derivatives 5a,b by cyclocondensation with 2-bromo-1-(4-chlorophenyl) ethanone. Treatment of 4a,b with base afforded 1,2,4-triazoles 6a,b. The synthesis of 1,3-oxazolidine 7 was performed by the reaction of compound 4a with ethyl bromoacetate. Treatment of 4a with acid produced 1,3,4-thiadiazole 8. The reaction of compounds 6a and 6b with several heterocyclic amines in the presence of formaldehyde gave the corresponding Mannich bases 9-15 containing various pharmacophore groups. Conventional and microwave-assisted methods were used for the synthesis. The effect of an acid catalyst on Mannich reactions was investigated. The structures of the newly synthesized compounds were elucidated on the basis of H-1 NMR, C-13 NMR, FTIR, EIMS techniques, and elemental analysis. All compounds were screened for their antimicrobial activity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 6704-31-0 help many people in the next few years. Recommanded Product: Oxetan-3-one.

Polyols and Rigid Polyurethane Foams from Cashew Nut Shell Liquid

Cashew nut shell liquid (CNSL) is a natural aromatic oil consisting of a mixture of phenolic structures with a carboxyl group in ortho position and substituted in meta position with a hydrocarbon chain of 15 carbon atoms. The major component of CNSL is anacardic acid (90 %), which is easily decarboxylated to cardanol by distillation. The present work describes the synthesis of new biobased Mannich polyols for rigid polyurethane foams in two steps: synthesis of Mannich bases by reacting phenolic ring of cardanol with N-(2-hydroxyethyl)-1,3-oxazolidine followed by alkoxylation reactions. The polyols were characterized by wet methods (hydroxyl numbers, viscosity, acid value, density, water content, iodine value etc.), spectroscopic methods (FT-IR, H-1 NMR and C-13 NMR) and by Gel Permeation Chromatography. The Mannich polyols from cardanol are excellent replacements for petrochemical derived Mannich polyols based on nonyl phenol. Cardanol-based polyols were used successfully for the preparation of rigid polyurethane foams of good physical-mechanical and fireproofing properties.

A novel synthesis of 2-alkyl(aryl)pyrrolidines from proline via 2,3-diphenylhexahydropyrrolo[2,1-b]oxazoles

Diphenyloxapyrrolizidines, products of the reaction between proline and benzaldehyde, are convenient building blocks for synthesizing 2-substituted pyrrolidines. The opening of their oxazolidine ring by treatment with Grignard reagents has been performed and conditions for subsequent removal of the N-hydroxyethyl moiety have been found. Though the yields are moderate (36-42%), the suggested synthesis of 2-alkyl(aryl)pyrrolidines is rather simple since it does not require purification of intermediate products and is easy scalable.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 84793-24-8. Formula: C16H19NO5.

Design and synthesis of a folate-receptor targeted diazepine-ring-opened pyrrolobenzodiazepine prodrug conjugate

Pyrrolobenzodiazepines (PBDs) and their dimers (bis-PBDs) have emerged as some of the most potent chemotherapeutic compounds and are currently under development as novel payloads in antibody-drug conjugates (ADCs). However, when used as stand-alone therapeutics or as warheads for small molecule drug conjugates (SMDCs), dose-limiting toxicities are often observed. As an elegant solution to this inherent problem, we designed and synthesized a diazepine-ring-opened bis-PBD prodrug (pro-PBD-PBD) folate conjugate lacking the one of the two imine moieties found in the corresponding free bis-PBD. Upon entering a targeted cell, cleavage of the linker system, including the hydrolysis of an oxazolidine moiety, results in the formation of a reactive intermediate which possesses a newly formed aldehyde as well as an aromatic amine. A fast and spontaneous intramolecular ring-closing reaction subsequently takes place as the aromatic amine adds to the aldehyde with the loss of water to give the imine, and as a result, the diazepine ring, thereby delivering the bis-PBD to the targeted cell. The in vitro and in vivo activity of this conjugate has been evaluated on folate receptor positive KB cells. Sub-nanomolar activity with good specificity and high cure rates with minimal toxicity have been observed.
