An efficient route for the synthesis of N-(1H-benzo[d]imidazol-2-yl)benzamide derivatives promoted by CBr<inf>4</inf> in one pot
2020, TetrahedronCitation Excerpt :Obviously, rich drug activities lead to lots of interests in synthesizing this skeleton. Existing ways to synthesize N-(1H-benzo[d]imidazol-2-yl)benzamide derivatives typically involved many defects, such as multi-step reactions [10], harsh conditions like strong bases [11] and transition metal catalysts [12]. To our knowledge, the formation of carbon-nitrogen bonds should be an effective strategy to build this skeleton.

Furthermore, they exhibit several other pharmacological activities including anti-diabetic [11], antifungal [12,13] anti-inflammatory, analgesic [14,15], antihistamine [16], antiviral [17], chemotherapeutic [18], antiparasitic [19,20] selective neuropeptide YY1 receptor antagonists [21], antimalarial, antitubercular [22], antiulcer [23], applications, and also find applications in materials chemistry as photochromic agents [24], and as fluorescent bleaching agent dyes such as 1,4-bis(benzo-xazolyl-2-yl) naphthalene and arenes [25]. Synthesis of benzimidazole core structure has received more and more attention in recent years.

2017, Tetrahedron LettersAntinociceptive effect of co-administered NMDA and histamine H4 receptor antagonists in a rat model of acute pain
2017, Pharmacological ReportsCitation Excerpt :This underlines the importance of H4R signaling in the absence of pathological inflammation or neuropathy. One paper by Galeotti et al. [31] demonstrates that agonist-induced H4R activation at the CNS level mediates antinociception in naïve mice and is reversed by JNJ10191584, a potent and highly selective H4R antagonist [52]. This finding clearly contrasts with our observations where we saw a clear antinociceptive response in both nociceptive tests.
