Undoubtedly, efficient cancer treatment has been a significant challenge for the scientific
community over the last decades. Despite tremendous progress made towards this direction, there are
still efforts needed to discover new anticancer drugs. In this work, a series of N-substituted pyrrolebased
scaffolds have been synthesized and evaluated for antiproliferative activity against a panel of
cancer cell lines (L1210, CEM and HeLa). Furthermore, in order to discover new scaffolds as antiviral agents, all the examined
compounds were evaluated for activity against different types of DNA and RNA viruses. The key feature of the
above structures is the existence of an aromatic ring with at least one hydrogen-bonding donor and acceptor group. Results
have shown noteworthy cytostatic activity for three of the synthesized compounds (1, 3 and 9). Especially, compound
1, containing a tropolone ring, proved to be the most promising scaffold (IC50:10-14 µM ) for the development of
novel potential anticancer agents. In addition, compound 1 has shown modest anti-HSV-1, -HSV2 activity in HEL cell
cultures (EC50: 27-40 µM).
毫无疑问,高效的癌症治疗在过去几十年里一直是科学界面临的重大挑战。尽管在这方面取得了巨大的进展,但仍需要努力发现新的抗癌药物。在这项研究中,合成了一系列N取代吡咯基框架,并评估其对一组癌细胞系(L1210、CEM和HeLa)的抗增殖活性。此外,为了发现新的作为抗病毒剂的框架,所有被检验的化合物都被评估了对不同类型的DNA和RNA病毒的活性。这些结构的一个关键特征是存在一个含有至少一个氢键供体和受体基团的芳香环。结果显示,合成的三种化合物(1、3和9)具有显著的细胞静止活性。特别是,含有特罗波隆环的化合物1被证明是最有前景的框架(IC50:10-14 μM),适用于开发新的潜在抗癌药物。此外,化合物1在HEL细胞培养中表现出中等的抗HSV-1和HSV-2活性(EC50:27-40 μM)。
