A series of β-Carboline derivatives were designed, synthesized, and evaluated for their fungicidal activities in this study. Several derivatives electively exhibited fungicidal activities against some fungi. Especially, compound F5 exhibited higher fungicidal activity against Rhizoctonia solani (53.35%) than commercial antiviral agent validamycin (36.4%); compound F16 exhibited high fungicidal activity against Oospora citriaurantii ex Persoon (43.28%). Some of the alkaloids and their derivatives (compounds F4 and F25) exhibited broad-spectrum fungicidal activity. Specifically, compound F4 exhibited excellent high broad-spectrum fungicidal activity in vitro, and the curative and protection activities against P. litchi in vivo reached 92.59% and 59.26%, respectively. The new derivative, F4, with optimized physicochemical properties, obviously exhibited higher activities both in vitro and in vivo; therefore, F4 may be used as a new lead structure for the development of fungicidal drugs.

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.

Naturally occurring β-carbolines are known to have antitumor activities but with limited effectiveness. In order to improve their efficacy, a series of new hydroxamic-acid-containing β-carbolines connected via a hydroxycinnamic acid moitey (12a-f) were developed to incorporate histone deacetylase (HDAC) inhibition for possible synergistic effects. When evaluated in in vitro assays, most of the analogues showed significant antitumor activities against four human cancer cells. In particular, 12b showed the highest cytotoxic potency of the series, including drug-resistant Bel7402 cells, but had minimal effect on normal hepatic LO2 cells. These compounds also showed excellent inhibitory effects against HDAC1/6, which appear to contribute greatly to their antiproliferative properties. Compound 12b enhanced the acetylation levels of histone H3 and α-tubulin and induced greater cancer cell apoptosis than the FDA-approved HDAC inhibitor SAHA by regulating expression of apoptotic proteins Bax, Bcl-2, and caspase 3. Importantly, 12b also induced a significant amount of autophagic flux activity in Bel7402 cells by increasing the expression of Beclin-1 and LC3-II proteins and decreasing that of LC3-I and p62. Finally, 12b significantly inhibited PI3K/Akt/mTOR signaling, an important cell-growth-promoting pathway aberrantly activated in many cancers. Together, the results suggest that these hydroxamic-acid-containing β-carboline derivatives may be new leads for the discovery of agents for the treatment of human carcinoma cancers.

Utilizing a pharmacophore hybridization approach, we have designed and synthesized a novel series of 28 new heterobivalent β-carbolines. The in vitro cytotoxic potential of each compound was evaluated against the five cancer cell lines (LLC, BGC-823, CT-26, Bel-7402, and MCF-7) of different origin—murine and human, with the aim of determining the potency and selectivity of the compounds. Compound 8z showed antitumor activities with half-maximal inhibitory concentration (IC50) values of 9.9 ± 0.9, 8.6 ± 1.4, 6.2 ± 2.5, 9.9 ± 0.5, and 5.7 ± 1.2 μM against the tested five cancer cell lines. Moreover, the effect of compound 8z on the angiogenesis process was investigated using a chicken chorioallantoic membrane (CAM) in vivo model. At a concentration of 5 μM, compound 8z showed a positive effect on angiogenesis. The results of this study contribute to the further elucidation of the biological regulatory role of heterobivalent β-carbolines and provide helpful information on the development of vascular targeting antitumor drugs.

A series of novel β-carboline-based hydroxamate derivatives 12a-k were designed and synthesized, and their biological activities in a series of in vitro assays were evaluated. Several of these β-carboline derivatives not only showed excellent HDAC1/3/6 inhibitory effects, but also displayed significant antitumor activities against five human cancer cells. The most potent compound 12f demonstrated the highest anticancer potency against cancer cell lines with IC50 values of 0.53–1.56 μM, which was considerably more potent than harmine (IC50 = 46.7–55.3 μM) and also three-to ten-fold lower than that of SAHA (IC50 = 4.48–6.26 μM). Immunoblot analysis revealed that 12f dose-dependently inhibited histone H3 and α-tubulin acetylation, confirming its HDAC inhibitory effects. Moreover, 12f significantly arrested HepG2 cells at G2/M phase through inhibiting cell cycle related protein CDK1 and cyclin B in a concentration dependent manner. Interestingly, 12f also exerted strong anti-metastasis activity by simultaneously reducing the protein level of MMP2 and MMP9 and inhibiting MAPK signaling pathway.

A series of novel β-carbolinium bromides has been synthesized from easily accessible β-carbolines and 1-aryl-2-bromoethanones. The newly synthesized compounds were evaluated for their in vitro anticancer activity. Among the synthesized derivatives, compounds 16l, 16o and 16s exhibited potent anticancer activity with IC50values of 50= 3.16–7.93 μM). In order to test the mechanism of cell death, we exposed castration resistant prostate cancer cell line (C4-2) to compounds 16l and 16s, which resulted in increased levels of cleaved PARP1 and AO/EB staining, indicating that β-carbolinium salts induce apoptosis in these cells. Additionally, the most potent β-carbolines 16l and 16s were found to inhibit tubulin polymerization.
