Uses

Different sources of media describe the Uses of 1146-98-1 differently. You can refer to the following data:
1. antidiabetic
2. Anticoagulant.

Manufacturing Process

To a solution of 1.85 g of sodium in 40 ml of ethanol, was added 10 g of phthalide and 14.0 g of p-bromobenzaldehyde, and the reaction mixture was heated on the steam bath for one hour. Water was then added, and the alcohol was distilled off. Then after adding additional water, the reaction mixture was acidified with hydrochloric acid to precipitate the crude product, which was filtered off, dried and recrystallized from methanol. The 2-pbromophenylindandione is in the form of dark red crystals, having a melting point of 133-135°C.

Efficient and convenient synthesis, characterization, and antimicrobial evaluation of some new tetracyclic 1,4-benzothiazines

In the present study, 20 new tetracyclic 1,4-benzothiazines (4a-4 t) were conveniently synthesized in good yields and characterized by different spectral and physical techniques. The in vitro antimicrobial evaluation of the synthesized benzothiazine derivatives was performed by serial dilution against two Gram-positive bacteria [Bacillus subtilis (MTCC 441) and Staphylococcus epidermidis (MTCC 6880)], two Gram-negative bacteria [Escherichia coli (MTCC 1652) and Pseudomonas aeruginosa (MTCC 424)], and two fungal strains [Candida albicans (MTCC 227) and Aspergillus Niger (MTCC 8189)]. The derivatives 4 l and 4 t were found to be more potent than standard drug, i.e., fluconazole, against A. Niger and C. albicans, respectively.

INDANONE AND INDANDIONE DERIVATIVES AND HETEROCYCLIC ANALOGS

The invention relates to indanone/indandione derivatives and heterocyclic analogs of Formula (I) wherein Ar1, A, B, L1, Y, Z, and (R1)n n are as described in the description; to pharmaceutically acceptable salts thereof, and to the use of such compounds as medicaments, especially as NPS receptor antagonists.

Formation of 2-arylindane-1,3-diones and 3-alkylphthalides from methyl o-[α-phenylsulfonyl]toluate

2-Aryl-1,3-indanedione and phthalide derivatives have attracted considerable interest due to their anticoagulant, parasiticidal and a range of biological activities. The synthesis of 2-aryl-1,3-indanedione by the condensation of the title sulfone with aryl aldehydes through an interesting pathway and a previously unreported approach to 3-alkylphthalide from C-alkylated derivatives of 1 under microwave and conventional heating conditions are described.

Hypolipidemic Activity of Indan-1,3-dione Derivatives in Rodents

A series of 2-substituted indan-1,3-dione derivatives, including alkyl (C-1-C-5), mono- and disubstituted phenyl, and other 2-aryl derivatives, were tested for hypolipidemic activity of CF1 male mice at 20 mg/kg per day.These derivatives reduced both serum cholesterol and triglycerides after 16 days of administration intraperitoneally. 2-(4-Methoxyphenyl)indan-1,3-dione was one of the more active compounds with 41percent reduction of serum cholesterol and 58percent reduction of serum triglyceride levels on day 16.This activity was confirmed in the rat after oral administration. 2-(2-Methylphenyl)- and 2-(4-chlorophenyl)indan-1,3-dione were effective in reducing serum triglyceride levels 58percent and 53percent, respectively, in mice.Serum cholesterol on day 16 was effectively reduced 46percent by 2-(2,4-dimethylphenyl)indan-1,3-dione.The indan-1,3-dione derivatives were more effective than clofibrate in lowering lipid levels in mice.A more detailed study on the effects of 2-(4-methoxyphenyl)indan-1,3-dione demonstrated that key enzymes in the de novo synthesis of lipids were inhibited by the drug lowering tissue levels of lipids but raising those in the feces.The alterations in lipid content of rat lipoprotein fractions by the drug appeared favorable.
