On the basis of the scaffolds widely used in drug design, a series of novel spirooxindole derivatives containing hydantoin, thiohydantoin, urea, and thiourea moieties have been designed, synthesized, characterized, and first evaluated for their biological activities. The diastereoselectivity mechanism is proposed, and the systematic conformational analysis is performed. The bioassay results show that the target compounds possess moderate to good antiviral activities against tobacco mosaic virus (TMV), among which compound 22 shows the highest antiviral activity in vitro as well as inactivation, curative, and protection activities in vivo (45 ± 1, 47 ± 3, 50 ± 1, and 51 ± 1%, 500 mg/L, respectively), higher than ribavirin (38 ± 1, 36 ± 1, 38 ± 1, and 36 ± 1%, 500 mg/L, respectively). Thus, compound 22 is a promising candidate for anti-TMV development. Most of these compounds show broad-spectrum fungicidal activities against 14 kinds of phytopathogenic fungi and selective fungicidal activities against Physalospora piricola, Sclerotinia sclerotiorum, and Rhizoctonia cerealis. Additionally, some of these compounds exhibit insecticidal activity against Culex pipiens pallens, Mythimna separata, Helicoverpa armigera, and Pyrausta nubilalis. Compound 17 exhibits the highest larvicidal activity (LC50 was 0.32 mg/L) against C. pipiens pallens.

On the basis of the biosynthesis of alkaloids derived from tryptophan and considering the wide use of spirooxindole in drug molecular design, a series of novel spirooxindole derivatives containing an acylhydrazone moiety were designed, synthesized, and first evaluated for their biological activities. The results of bioassays indicated that the target compounds possessed good activities against tobacco mosaic virus (TMV); especially compound 4, containing a tert-butyl at the benzene ring, exhibited the best antiviral activity in vitro and inactivation, curative, and protection activities in vivo (48.4%, 58 ± 0.4, 55.2 ± 2.3, and 49.7 ± 1.1% at 500 μg/mL, respectively) compared with ribavirin (38.2, 36.4 ± 0.2, 37.5 ± 0.2, and 36.4 ± 0.1% at 500 μg/mL, respectively) and harmine (44.6, 40.5 ± 0.2, 38.6 ± 0.8, and 42.4 ± 0.6% at 500 μg/mL, respectively). At the same time, these compounds exhibited fungicidal activity selectively against certain fungi; most of these derivatives exhibited >60% fungicidal activity against Physalospora piricola at 50 mg/kg. Additionally, compounds 25 and 14 displayed excellent insecticidal activities (60% motality against C. pipiens pallens at 0.25 mg/kg) even at very low concentrations.

The cytotoxicity properties of the β-carboline alkaloids have been broadly investigated. However, the potential application of β-carbolines was hindered due to the moderate activity in cancer. In the present study, thirty β-carboline-(phenylsulfonyl)furoxan hybrids (11a–j, 12a–j and 13a–j) were designed and synthesized through esterification and amidation reaction strategy, and their inhibitory activities against the human breast cancer cell lines MCF-7 and MDA-MB-231 were evaluated by CCK-8 assay. Biological evaluation presented that the most promising amide derivative 13h, substituted with p-methoxyphenyl group at position 1, generated high concentration of NO and evidently depressed the MCF-7 (IC50 = 0.89 μM) and MDA-MB-231 (IC50 = 0.62 μM) cells proliferation. Particularly, the wound healing and transwell assays demonstrated that 13h significantly inhibited the migration and invasion of MDA-MB-231cells. Furthermore, the preliminary mechanisms studies indicated that 13h induced G2/M phase arrest and apoptosis possibly causing by ROS accumulation and ROS-mediated DNA damage. Based on these considerations, 13h may be a promising antimetastatic agent for breast cancer, which is noteworthy for further exploration.

Natural β-carboline alkaloids are ideal models for the discovery of pharmaceutically important entities. Various 1-substituted β-carbolines were synthesized from commercially inexpensive tryptophan and demonstrated significant in vitro antifungal activity against G. graminis. Significantly, compound 4m (EC50 = 0.45 μM) with carboxamide at 1-position displayed the best efficacy and nearly 20 folds enhancement in antifungal potential compared to Silthiopham (EC50 = 8.95 μM). Moreover, compounds 6, 7, and 4i exhibited excellent in vitro antifungal activities and in vivo protective and curative activities against B. cinerea and F. graminearum. Preliminary mechanism studies revealed that compound 4m caused reactive oxygen species accumulation, cell membrane destruction, and deregulation of histone acetylation. These findings indicated that 1-carbamoyl β-carboline can be selected as a promising model for the discovery of novel and broad-spectrum fungicide candidates.

A series of N-acylhydrazone-linked, heterobivalent β-carboline derivatives was designed and synthesized from L-tryptophan in a nine-step reaction sequence. The effort resulted in the heterobivalent β-carbolines 10a–t in good yields. The target compounds were characterized by 1H NMR, 13C NMR and high-resolution mass spectrometry (HRMS). The in vitro cytotoxic activity of the synthesized compounds was evaluated against normal EA.HY926 cells and five cancer cell lines: LLC (Lewis lung carcinoma), BGC-823 (gastric carcinoma), CT-26 (murine colon carcinoma), Bel-7402 (liver carcinoma), and MCF-7 (breast carcinoma). Compound 10e, with an IC50 value of 2.41 μM against EA.HY926 cells, was the most potent inhibitor. It showed cytotoxicity against all five cancer cell lines of different origin – murine and human, with IC50 values ranging from 4.2 ± 0.7 to 18.5 ± 3.1 μM. A study of structure-activity relationships indicated that the influence on cytotoxic activities of the substituent in the R9′-position followed the tendency, 2,3,4,5,6-perfluorophenylmethyl > 4-fluorobenzyl > 3-phenylpropyl group. The antitumor efficacies of the selected compounds were also evaluated in mice. Compound 10e exhibited potent antitumor activity, with tumor inhibition of more than 40% for Sarcoma 180 and 36.7% for Lewis lung cancer. Furthermore, the pharmacological mechanisms showed that compound 10e has a certain impairment in the motility of LLC cells, which suggests the anti-metastatic potential. And compound 10e inhibited angiogenesis in chicken chorioallantoic membrane assay, and the anti-angiogenetic potency was more potent than the reference drug combretastatin A4-phosphate (CA4P) at a concentration 50 μM.
