The oral administration of clioquinol – a potent 8-hydroxyquinoline antimicrobial drug – was forbidden due to suspicion of it being the cause of SMON (subacute myelo-optic-neuropathy) in Japan. However, this adverse effect was only observed in Japan, despite the fact that the drug was used worldwide. In addition, studies have shown that vitamin B12 deficiency could be involved in this process. Thus, the interest in the modification of this compound has recently emerged as a strategy to find new drug candidates. In the present work, we have designed and synthesized a novel series of clioquinol derivatives by the modification of the 7-position of this compound Twenty-one derivatives were prepared from com. available clioquinol in two or three steps: 8-OH-protection of clioquinol followed by the palladium-catalyzed cross-coupling reaction to introduce the arylamine group at position 7 resulting in derivatives 4a-4j. Finally, deprotection of the hydroxyl group gave derivatives 5a-5i and 10a-10b. The compounds prepared were tested against Candida spp. and dermatophyte isolates by the broth microdilution method. We have found a clear structure-activity relationship. The presence of free hydroxyl in the 8-position and the introduction of the hydrophilic heterocyclic substituent at the 7-position are important for the antifungal activity of this class. Moreover, the introduction of dimethoxy groups at the pyrimidinyl ring attached to the 7-position seems to be promising against dermatophytes and Candida albicans. Among all derivatives, compound 5h presented interesting activity against all fungal species tested (with MIC values of 4 渭g mL-1), along with low toxicity in normal cells. This derivative is non-irritant with the absence of topical toxicity. In addition, 5h does not seem to act as an ionophore in fungal cells, similarly to clioquinol. These compounds appear to have a scavenger effect, which suggests their selectivity for fungal cells. Taken together, these findings indicate the potential of 5h to be developed as an antifungal agent.
Quality Control of 109-12-6, 2-Aminopyrimidine is a useful research compound. Its molecular formula is C4H5N3 and its molecular weight is 95.1 g/mol. The purity is usually 95%.
2-Aminopyrimidine is an organic compound that belongs to the group of pyridines. It has been shown to have antimicrobial, antitumor, and antiviral properties. 2-Aminopyrimidine has been used as a fungicide and herbicide in horticulture and agriculture, respectively. The molecular geometry of this molecule is octahedral with coordination geometry C2v. This chemical binds to the BCR-ABL kinase receptor and inhibits its activity by competitive inhibition of ATP binding. 2-Aminopyrimidine has been shown to have a hematologic response in vivo models and in vitro assays. It also has anti-inflammatory effects when it is taken orally or applied topically., 109-12-6.
