Polymer-Supported Sulfonic Acid-Catalyzed Candid Synthesis and Photophysical Properties of 2H-indazolo[2,1-b]phthalazinetriones

Polystyrene-supported sulfonic acid has been found to be an efficient catalyst for the one-pot, three-component synthesis of 2H-indazolo[2,1-b]phthalazinetriones in greener solvent glycerol. Use of greener solvent glycerol along with a polymer-supported, low toxic, and inexpensive catalyst renders the method eco-friendly. High yields, simple product isolation procedure, and fluorescent and electroluminescent natures of the products are the noteworthy aspects of this protocol.

Synthesis and evaluation of new phthalazine substituted beta-lactam derivatives as carbonic anhydrase inhibitors

A new series of phthalazine substituted beta-lactam derivatives were synthesized and their inhibitory effects on the activity of purified human carbonic anhydrase (hCA I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and the nitro group was reduced to 13-(4-aminophenyl)-3,3-dimethyl-3,4-dihydro-2H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione with SnCl2 center dot 2H(2)O. The reduced compound was reacted with different aromatic aldehydes, and phthalazine substituted imines were synthesized. The imine compounds undergo (2+2) cycloaddition reactions with ketenes to produce 2H-indazolo[2,1-b]phthalazine-trione substituted beta-lactam derivatives. The beta-lactam compounds were tested as inhibitors of the CA isoenzyme activity. The results showed that all the synthesized compounds inhibited the CA isoenzyme activity. 1-(4-(3,3-dimethyl-1,6,11-trioxo-2,3,4,6,11,13-hexahydro-1H-indazolo[1,2b]phthalazin-13-yl)phenyl)-2-oxo-4-p-tolylazetidin-3-yl acetate (IC50 = 6.97 A mu M for hCA I and 8.48 A mu M for hCA II) had the most inhibitory effect.

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 622-88-8, in my other articles. SDS of cas: 622-88-8.

An improved procedure for the three-component synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives using basic ionic liquid

An efficient and green method for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been achieved through the one-pot, three-component condensation of aromatic aldehydes, malononitrile or ethyl cyanoacetate, and phthalhydrazide in the presence of 1-butyl-3-methyl imidazolium hydroxide ([bmim]OH) as catalyst in EtOH. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionic liquid can be recovered and recycled for subsequent reactions. Moreover, this protocol has the advantages of easy work-up, short reaction time, mild reaction conditions and environmentally benign procedures compared with the reported methods.

Antibacterial Evaluation of Some 3-Amino-1H-Pyrazolo[1,2-b]Phthalazine-2-Carboxamides by using Fish Scale Hydroxyapatite as a Heterogeneous Catalyst

Fish scale hydroxyapatite (FS-HAP) has been used as an efficient catalyst for the synthesis of 3-amino-1H-pyrazolo[1,2-b]phthalazine-2-carboxamide derivatives via the one-pot, three-component cyclocondensation reactions of aromatic aldehydes with cyanoacetamide and phthalhydrazide under solvent-free condition. FS-HAP has been characterized by FT-IR, XRD, SEM and EDS techniques. The synthesized compounds were evaluated for their in vitro antibacterial activity against gram-positive (Bacillus cereus, Bacillus aryabhattai, Bacillus megaterium, Staphylococcus aureus) and gram-negative (Serratia marcescens, Bacillus Pseudomonas putida, Escherichia coli, Enterobacter cloacae) bacteria. Tetracycline and erythromycin were used as standard antibiotics in this investigation. In the present protocol, we have achieved remarkable yields of the product in shorter reaction time and the catalyst was easily recovered and reused.
