  We have disclosed our effort to develop caffeic acid derivatives as potent and non-toxic inhibitors of α-MSH-stimulated melanogenesis to treat pigmentation disorders and skin medication including a cosmetic skin-whitening agent. The SAR studies revealed that cyclohexyl ester and secondary amide derivatives of caffeic acid showed significant inhibitory activities.

  Fungal infections remain a high-incidence worldwide health problem that is aggravated by limited therapeutic options and the emergence of drug-resistant strains. Cinnamic and benzoic acid amides have previously shown bioactivity against different species belonging to the Candida genus. Here, 20 cinnamic and benzoic acid amides were synthesized and tested for inhibition of C. krusei ATCC 14243 and C. parapsilosis ATCC 22019. Five compounds inhibited the Candida strains tested, with compound 16 (MIC = 7.8 µg/mL) producing stronger antifungal activity than fluconazole (MIC = 16 µg/mL) against C. krusei ATCC 14243. It was also tested against eight Candida strains, including five clinical strains resistant to fluconazole, and showed an inhibitory effect against all strains tested (MIC = 85.3–341.3 µg/mL). The MIC value against C. krusei ATCC 6258 was 85.3 mcg/mL, while against C. krusei ATCC 14243, it was 10.9 times smaller. This strain had greater sensitivity to the antifungal action of compound 16. The inhibition of C. krusei ATCC 14243 and C. parapsilosis ATCC 22019 was also achieved by compounds 2, 9, 12, 14 and 15. Computational experiments combining target fishing, molecular docking and molecular dynamics simulations were performed to study the potential mechanism of action of compound 16 against C. krusei. From these, a multi-target mechanism of action is proposed for this compound that involves proteins related to critical cellular processes such as the redox balance, kinases-mediated signaling, protein folding and cell wall synthesis. The modeling results might guide future experiments focusing on the wet-lab investigation of the mechanism of action of this series of compounds, as well as on the optimization of their inhibitory potency.

  真菌感染仍然是全球高发的健康问题，由于治疗选择有限和药物耐药菌株的出现而加剧。曾经显示出对属于念珠菌属不同物种具有生物活性的肉桂酸和苯甲酸酰胺。在这里，合成了20种肉桂酸和苯甲酸酰胺，并对C. krusei ATCC 14243和C. parapsilosis ATCC 22019的抑制进行了测试。五种化合物抑制了测试的念珠菌菌株，其中化合物16（MIC = 7.8 µg/mL）对C. krusei ATCC 14243的抗真菌活性比氟康唑（MIC = 16 µg/mL）更强。它还被测试对抗包括五种对氟康唑耐药的临床菌株在内的八种念珠菌菌株，显示出对所有测试菌株的抑制作用（MIC = 85.3-341.3 µg/mL）。对C. krusei ATCC 6258的MIC值为85.3 mcg/mL，而对C. krusei ATCC 14243的MIC值则小了10.9倍。这株菌株对化合物16的抗真菌作用更为敏感。化合物2、9、12、14和15也能抑制C. krusei ATCC 14243和C. parapsilosis ATCC 22019的生长。进行了结合靶点预测、分子对接和分子动力学模拟的计算实验，以研究化合物16对C. krusei的潜在作用机制。从这些实验中，提出了这种化合物的多靶点作用机制，涉及与关键细胞过程相关的蛋白质，如氧化还原平衡、激酶介导的信号传导、蛋白质折叠和细胞壁合成。建模结果可能指导未来的实验，重点研究这一系列化合物的作用机制的湿实验调查，以及优化它们的抑制效力。

  A series of caffeic acid amides were designed, synthesized, and their synergistic activity with fluconazole against fluconazole-resistant Candida albicans was evaluated in vitro. The title caffeic acid amides 3-30 except 26 exhibited potent activity, and the subsequent SAR study was conducted. Compound 3, 5, 21, and 34c, at a concentration of 1.0 mu g/ml, decreased the MIC80 of fluconazole from 128.0 mu g/ml to 1.0-0.5 mu g/ml against the fluconazole-resistant C. albicans. This result suggests that the caffeic acid amides, as synergists, can sensitize drug-resistant fungi to fluconazole. The SAR study indicated that the dihydroxyl groups and the amido groups linking to phenyl or heterocyclic rings are the important pharmacophores of the caffeic acid amides. (C) 2014 Elsevier Ltd.
