<p>A new sesquilignan effususin E (1) and a new long chain fatty enamide effususin F (2), together with eight known compounds were isolated from the medullae of <em>Juncus effusus</em>. The structures of 1 and 2 were elucidated by detailed spectroscopic analysis including 1H and 13C NMR, COSY, HSQC, HMBC, and HRMS, while the struc-tures of the known compounds were deduced from comparison of their spectral data with those in the literature. The new compounds 1 and 2 were evaluated against five human cancer cell lines (SHSY-5Y, SMMC-7721, HepG-2, Hela, and MCF-7) by CCK-8 assay, but only 1 exhibited weak cytotoxic activity against SMMC-7721 with IC50 val-ue of 57.5 μM. Inhibitory effects of 1 and 2 on nitric oxide (NO) pro-duction in lipopolysaccharide-induced RAW264.7 macrophages were also evaluated, and they were found to exhibit good inhibitory activities with IC50 values of 8.59 and 13.73 μM, respectively.</p>

Four new compounds, including two new polyketides, heterocornols M and N (1, 2), and a pair of epimers, heterocornols O and P (3, 4), were isolated from the fermentation broth of the marine sponge-derived fungus Pestalotiopsis heterocornis XWS03F09, together with three known compounds (5–7). The new chemical structures were established on the basis of a spectroscopic analysis, optical rotation, experimental and calculated electronic circular dichroism (ECD). All of the compounds (1–7) were evaluated for their cytotoxic activities, and heterocornols M-P (1–4) exhibited cytotoxicities against four human cancer cell lines with IC50 values of 20.4–94.2 μM.

AbstractThree new bisindole alkaloids, 3′-(2-oxopropyl)-19,20-dihydrotabernamine (1), 3′-(2-oxopropyl)-ervahanine B (2), 19,20-dihydrovobparicine (3), and 20 known compounds were isolated from the aerial parts of Tabernaemontana bufalina. The structures of these alkaloids were elucidated using spectroscopic methods. The absolute configurations of 1–3 were determined by the circular dichroic exciton chirality method. Compounds 1–23 were screened for their cytotoxicity against two human cancer cell lines, A-549 and MCF-7. Ten compounds (1–3, 10, 14, 16, 17, 19, 22, and 23) exhibited inhibitory effects against the two human cancer cells with IC50 values of 1.19 ~ 6.13 µM.

The synthesis of a series of substituted hippuric acid (2-benzamidoacetic acid) derivatives containing arylsulfonylpiperazine nucleus (3a–j, 4a–j) is described. The compounds were synthesized by coupling hippuric/4-fluorohippuric acid with various arylsulfonylpiperazines using N-(3-dimethylaminopropyl)-N-ethylcarbodiimide (EDCI). The structures of all the new compounds were confirmed by IR, NMR and MS spectral data. All the synthesized compounds have been evaluated for their in vitro cytotoxicity towards five human cancer cell lines of different origins viz. HeLa (Cervical), A549 (Lung), A375 (Skin), MD-AMB-231(Breast) and T98G (brain) and their IC50 values were determined. Among the compounds tested, 3b, 3d, 3g, 4c and 4e displayed significant cytotoxic activity (IC50 = 24.2–38.2 µM). T98G was the most sensitive cell line towards the compounds studied followed by HeLa, A375, A549 and MD-AMB-231.

Two new steroidal alkaloids, named hookerianine A (1) and hookerianine B (2) were isolated from the stems and roots of Sarcococca hookeriana Baill., along with two known compounds, sarcorucinine G (3) and epipachysamine D (4). On the basis of spectroscopic methods and by comparison with literature data, their structures were determined. As well as X-ray crystallography was performed to confirm compound 4. To identify novel antitumor inhibitors, all compounds were performed a CCK-8 assay against five human cancer cell lines SW480, SMMC-7721, PC3, MCF-7 and K562 in vitro. Compound 2 exhibited moderate cytotoxic activities to all cell lines with IC50 values in the range of 5.97–19.44 μM. Compound 3 was the most effective one against SW480 and K562 cell lines with IC50 values of 5.77 and 6.29 μM, respectively.

A new monoterpenoid indole alkaloid, ochroborbone (1), along with five known alkaloids (2–6), were isolated from the stems and leaves of Ochrosia borbonica. Among them, ochroborbone (1) is a rare C17-nor monoterpenoid indole alkaloid, and the known compounds (2-6) were isolated from Ochrosia for the first time. These structures were established on the basis of extensive spectroscopic methods. All isolated compounds were evaluated for their cytotoxicities against five human cancer cell lines: HL-60, SMMC-7721, A-549, MCF-7 and SW480 in vitro. Compounds 1 and 2 exhibited inhibitory effects with IC50 values comparable with those of cisplatin.

A series of 30-diethylphosphate derivatives of betulin were synthesized and evaluated for their in vitro cytotoxic activity against human cancer cell lines, such as amelanotic melanoma (C-32), glioblastoma (SNB-19), and two lines of breast cancer (T47D, MDA-MB-231). The molecular structure and activities of the new compounds were also compared with their 29-phosphonate analogs. Compounds 7a and 7b showed the highest activity against C-32 and SNB-19 cell lines. The IC50 values for 7a were 2.15 and 0.91 μM, and, for 7b, they were 0.76 and 0.8 μM for the C-32 and SNB-19 lines, respectively. The most potent compounds, 7a and 7b, were tested for their effects on markers of apoptosis, such as H3, TP53, BAX, and BCL-2. For the whole series of phosphate derivatives, a lipophilicity study was performed, and the ADME parameters were calculated. The most active products were docked to the active site of the EGFR protein. The relative binding affinity of selected phosphate betulin derivatives toward EGFR was compared with standard erlotinib on the basis of ChemScore and KDEEP score. Positively, all derivatives docked inside the cavity and showed significant interactions. Moreover, a molecular dynamics study also reveals that ligands 7a,b form stable complexes and the plateau phase started after 7 ns.

In continuation of our study on anticancer compounds, a series of novel artemisinin dimers have been synthesized and evaluated for their cytotoxic effects against three human cancer cell lines, including HepG2 (liver cancer), MCF-7(breast cancer) and HL-60 (leukemia cancer). The assay results showed that most of the compounds displayed inhibitory effects against all three human cancer cell lines tested, and seemed to be more cytotoxic toward the blood cancer cells (HL-60) than liver (HepG2), and breast (MCF-7) cancer cells. Among the synthesized artemisinin dimers, the compound 10d with a double bond bridge exhibited the most potent cytotoxicity with IC50 values of 5.08, 4.82 and 1.32 µg/mL against the HepG2, MCF-7, and HL-60 cell lines, respectively.

A new series of s-triazine hydrazone derivatives was prepared based on the reaction of 6-hydrazino-2,4-disubstituted-s-triazine with p-substituted benzaldehyde derivatives using a straightforward synthetic pathway. The antiproliferative activity of all synthesized compounds was evaluated against two human cancer cell lines; breast cancer MCF-7 and colon carcinoma HCT-116 using MTT assay. Among all, 11 compounds have shown strong to moderate antiproliferative activity with IC50 values in the range 1.01–18.20 µM in MCF-7 and 0.97–19.51 µM in HCT-116. The best results were obtained with 4,4’-(6-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3,5-triazine-2,4-diyl) dimorpholine 11 (IC50 = 1.0 µM and 0.98 µM in MCF-7 and HCT-116 cell lines, respectively). The substituents on the s-triazine core as well as the substituent at the benzylidene moiety have a great effect on the antiproliferative activity. Whereas compounds containing dimorpholino-s-triazine derivatives 8a–e showed more potent antiproliferative in MCF-7 compared to their analogs 7a–f (compounds containing two-piperidine rings), compounds containing one piperidine and one morpholine ring 9a–f showed better IC50 values in the range 10.4–22.2 µM. On the other hand, compounds containing two-piperidine rings 7a–f showed more potent antiproliferative in HCT-116 (IC50 values in the range 8.8–19.5 µM) than their analogs 8a–e and 9a–f.
