The ring opening of some phthalimide derivatives with sodium borohydride in methanol/water (6:1) afforded the corresponding 2-hydroxymethylbenzamides irrespective of the substituents. The most active members of the series evaluated for anti-inflammatory and analgesic activities were 2-hydroxymethyl-N-[4-(2-methoxyphenyl)-piperazin-1-yl]-ethylbenzamide (3d) and 2-hydroxymethyl-N-[4-(2-methoxyphe...

In the field of organosulfur chemistry, sulfenylating agents are an important key in C–S bond formation strategies. Among various precursors, N -sulfenylsuccinimide/phthalimide derivatives have shown highly electrophilic reactivity for asymmetric synthesis many organic compounds. Hence, this review article, we focus on application these alternative reagents transformations.

Objective(s): Phthalimide-based derivatives have anticonvulsant activity like as phenytoin by inhibition of sodium channel. In our previously research we mentioned about some phthalimide derivatives as potent anticonvulsant agents. Materials and Methods: Fourteen analogs of 2-substituted phthalimide pharmacophore were synthesized and then were evaluated for the anticonvulsant activities in pent...

Pre-queuosine or queuine (preQ1) is a guanine derivative that is involved in the biosynthetic pathway of the hypermodified tRNA nucleoside queuosine (Que). The core structure of preQ1 is represented by 7-(aminomethyl)-7-deazaguanine (preQ1 base). Here, we report the synthesis of three preQ1 base derivatives with complementary (15)N-labeling patterns, utilizing [(15)N]-KCN, [(15)N]-phthalimide, ...

objective(s): recently, phthalimide derivatives were designed based on ameltolide and thalidomide as they possess a similar degree of anticonvulsant potency due to their phenytoin-like profile. the ability of phthalimide pharmacophore to interact with neuronal voltage-dependent sodium channels was studied in the batrachotoxin affinity assay. therefore, in the present study, a series of 19 compo...

The photochemistry of phthalimide derivatives of the electron-rich amino acids tyrosine, histidine and tryptophan 8-10 was studied with respect to photoinduced electron-transfer (PET) induced decarboxylation and Norrish II bond cleavage. Whereas exclusive photodecarboxylation of the tyrosine substrate 8 was observed, the histidine compound 9 resulted in a mixture of histamine and preferential N...

2-(6,8-Dibromo-2-methylquinazolin-4-yloxy)-acetohydrazide (4) was prepared by the reaction of 6,8-dibromo-2-methylbenzo-[d][1,3]oxazin-4-one with formamide to afford quinazolinone 2, followed by alkylation with ethyl chloroacetate to give the ester 3. Treatment of ester 3 with hydrazine hydrate and benzaldehyde afforded 4 and styryl quinazoline 5. The hydrazide was reacted with triethyl orthofo...
