Novel reactions of ninhydrin oxime with mercaptoalkanoic acids

Ninhydrin oxime and mercaptoalkanoic acids in the presence of trifluoroacetic acid form 2,2 ‘-spiranes incorporating indane-1,3-dione and 3-hydroxy-1,3-thiazolidin-4-one or 3-hydroxytetrahydro-1,3-thiazin-4-one moieties. On heating in acetic anhydride, the same reactants undergo replacement of oxime hydroxy group by sulfur thus affording thiooxime-containing alkanoic acids.

Synthesis, characterization, biological evaluation, and molecular docking studies of some piperonyl-based 4-thiazolidinone derivatives

Heterocyclic compounds are of particular importance among pharmacologically active compounds. In this study, some piperonyl-based 4-thiazolidinone derivatives (2a-i) were synthesized and characterized by spectroscopic assays. All molecules were tested as enzyme inhibitory factors. These compounds were effective inhibitors of the enzymes acetylcholinesterase (AChE), alpha-glycosidase (alpha-Gly), and the human carbonic anhydrase I and II isoforms (hCA I and II), with K-i values in the range of 8.90-66.51 nM for alpha-Gly, 94.8-289.5 nM for hCA I, 106.3-304.6 nM for hCA II, and 0.55-2.36 nM for AChE. The synthesized molecules were also studied theoretically. Molecular docking calculations were performed to investigate the interaction between the target protein and molecules. CA inhibitor compounds have been clinically used for almost 60 years as antiglaucoma and diuretic drugs. The inhibition of the AChE enzyme results in the blockage of ACh hydrolysis. On the contrary, the design of inhibitor compounds or/and modulators for AChE is of major interest as it is one of the most popular tools to prevent Alzheimer’s disease.

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 99-86-5. Application In Synthesis of 1-Isopropyl-4-methylcyclohexa-1,3-diene.

Redetermination of the crystal structure of 2-oxo-1,3-thiazolidin-4-iminium chloride

In the redetermination of the title compound, C3H5N2OS+center dot CI-, the asymmetric unit consists of one independent 2-oxo-1,3-thiazolidin-4-iminium cation and one independent chloride anion. The cation interacts with a chloride anion via N-H center dot center dot center dot Cl hydrogen bonds forming a supramolecular chain along [010]. These supramolecular chains are further extended by weak C-H center dot center dot center dot Cl and C-H center dot center dot center dot O interactions, forming a two-dimensional network parallel to (001). The crystal structure is further stabilized by weak C-O center dot center dot center dot pi interactions, supporting a three-dimensional architecture. The structure was previously determined by Ananthamurthy & Murthy [Z. Kristallogr. (1975). 8, 356-367] but has been redetermined with higher precision to allow the hydrogen-bonding patterns and supramolecular interactions to be investigated.

SYNTHETIC APPROACH FOR BUILDING HETEROANNULATED FURO[3,2-g]CHROMENES USING 4,9-DIMETHOXY-5-OXO-5H-FURO[3,2-g]CHROMENE-6-CARBONITRILE AND CYCLIC CARBON NUCLEOPHILE

A novel series of polyfused heterocyclic systems containing furo[3,2-g]chromenes were efficiently synthesized. The reactivity of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]chromene-6-carbonitrile (1) was studied towards a variety of carbon nucleophilic reagents such as heterocyclic enols, heterocyclic enamines and cyclic active methylene compounds. Treatment of carbonitrile 1 with 4-hydroxycoumarin, 4-hydroxy-1-methylquinolin-2(1H)-one (3), 2-hydroxy-4H-pyrido[1,2-a]pyrimidin-4-one (4) afforded furodichromenopyridine 2, furochromenonaphthyridine 5, furochromenodipyridopyrimidine 6. Reaction of carbonitrile 1 with 4(6)-aminouracil and 5-amino-3-methyl-1H-pyrazole proceed through ring opening followed by cycloaddition into the nitrile group giving pyrido[2,3-d]pyrimidine 7 and pyrazolo[3,4-b]pyridine 8. Also, reaction of carbonitrile 1 with 5-amino-2,4-dihydro-3H-pyrazol-3-one (9), 2-(phenylimino)-1,3-thiazolidin-4-one (11), thiobarbituric acid and cyclohexane-1,3-dione produced the novel annulated furo[3,2-g]chromenes 10, 12-14, respectively. Cyclohexane-1,2-dione reacted with carbonitrile 1 in 1:2 molar ratio afforded bis-(furochromeno)[1,10]phenanthroline 15. The prepared compounds were screened in vitro for their antimicrobial activity and some of them appeared notable activity against the tested microorganisms.
