A series of saccharide-modified thiadiazole sulfonamide derivatives has been designed and synthesized by the “tail approach” and evaluated for inhibitory activity against carbonic anhydrases II, IX, and XII. Most of the compounds showed high topological polar surface area (TPSA) values and excellent enzyme inhibitory activity. The impacts of some compounds on the viability of HT-29, MDA-MB-231, and MG-63 human cancer cell lines were examined under both normoxic and hypoxic conditions, and they showed certain inhibitory effects on cell viability. Moreover, it was found that the series of compounds had the ability to raise the pH of the tumor cell microenvironment. All the results proved that saccharide-modified thiadiazole sulfonamides have important research prospects for the development of CA IX inhibitors.

A series of benzo [d] [1,3] azoles 2-substituted with benzyl- and allyl-sulfanyl groups were synthesized, and their cytotoxic activities were in vitro evaluated against a panel of six human cancer cell lines. The results showed that compounds BTA-1 and BMZ-2 have the best inhibitory effects, compound BMZ-2 being comparable in some cases with the reference drug tamoxifen and exhibiting a low cytotoxic effect against healthy cells. In silico molecular coupling studies at the tamoxifen binding site of ERα and GPER receptors revealed affinity and the possible mode of interaction of both compounds BTA-1 and BMZ-2.

A new cyclolanostane triterpenoid xyloside, soulieoside P (1), and a known oleanane-type saponin, hederasaponin B (2), were isolated from the rhizomes of Souliea vaginata. Their structures were established by extensive spectroscopic and HRESIMS analysis, as well as chemical methods. Compound 1 showed significant inhibitory effects with IC50 values of 7.6–11.2 μM against three human cancer cell lines, while compound 2 exhibited no hepatoprotective effect on CCl4-induced injury of human HepG2 cells, in the tested range of 0.1–100 μM.

A series of new 3-phenyl-5-aryl-N-(4-sulfamoylphenyl)-4,5-dihydro-1H-pyrazole-1-carboxamide derivatives was designed here, synthesized, and studied for carbonic anhydrase (CAs, EC 4.2.1.1) inhibitory activity against the human (h) isozymes I, II, and VII (cytosolic, off-target isoforms), and IX and XII (anticancer drug targets). Generally, CA I was not effectively inhibited, whereas effective inhibitors were identified against both CAs II (KIs in the range of 5.2–233 nM) and VII (KIs in the range of 2.3–350 nM). Nonetheless, CAs IX and XII were the most susceptible isoforms to this class of inhibitors. In particular, compounds bearing an unsubstituted phenyl ring at the pyrazoline 3 position showed 1.3–1.5 nM KIs against CA IX. In contrast, a subset of derivatives having a 4-halo-phenyl at the same position of the aromatic scaffold even reached subnanomolar KIs against CA XII (0.62–0.99 nM). Docking studies with CA IX and XII were used to shed light on the derivative binding mode driving the preferential inhibition of the tumor-associated CAs. The identified potent and selective CA IX/XII inhibitors are of interest as leads for the development of new anticancer strategies.

Aims: Apocynaceae family is the 5th largest medicinal plant family rich in potent secondary metabolites such as Alkaloids, Cardiac glycosides,Terpenoids, irridoid/secoirridoids, flavonoids and Phenolic contents. The present study was aimed to evaluate and compare in-vitroantiproliferative activity of three plants of this family.Methods: Aerial parts of Carissa carandas Linn. (C), Nerium indicum Mill. (N) and Wrightia tinctoria RBr. (W), were collected and dried. Thepowdered drugs were extracted in Ethanol (1), 60% Ethanol (2) and Water (3). Estimation of Phytoconstituents performed using standardmethods. In-vitro cytotoxic activity performed using Sulphorhodamine B (SRB) assay in HepG2, HT29 and SKOV3 human cancer cell lines takingAdriamycin (ADR) as standard. For extracts, GI50 value ≤ 20μg/ml was considered to demonstrate activity.Results: For HepG2 cell line graphs and photomicrographs showed GI50 value as ADR=39.79, C1=2.5, N2=66.3, N3<10 and C2=C3= N1=W1-3>80. Also TGI for C1>80. The extracts, C1, C2, N1, N2, and N3 were found to possess activity against HepG2.These extracts were screened onHT 29 and SKOV3cell lines. The GI50 value observed was<10 for C1, N2, N3 and ADR in HT 29 and <10 for N3 and ADR in SK OV3 cell lines.Thus it was found that aqueous extract of Nerium indicum (N3) and Ethanolic extract of Carissa carandas (C1) were most cytotoxic extractsagainst all three cell lines.Conclusions: our study establishes that Apocynaceae family plants could be an important anticancer lead and could serve as Botanical drug forneoplasia.Keywords: Apocynaceae, SRB Assay, Phytoconstituents, Anticancer drug screening models, Hep G2, HT 29, SK-OV3, HCC.

From the whole plant of Dendrobium signatum, a new bibenzyl-dihydrophenanthrene derivative, named dendrosignatol was isolated, together with the known compounds 3,4-dihydroxy-3,4′-dimethoxybibenzyl, dendrocandin B, dendrocandin I and dendrofalconerol A. The structure of the new compound was elucidated through analysis of its spectroscopic and mass spectrometric data. All of the isolates showed appreciable cytotoxic activity against three human cancer cell lines, including MDA-231, HepG2 and HT-29 cells.

AbstractSynthesis of tubulysin analogues, containing an N-methyl substituent on tubuvaline-amide together with the replacement of either the hydrophobic N-terminal N-methyl pipecolic acid (Mep) or at both N- and C- terminal peptides with available heteroaromatic acids and an unsaturated tubuphenylalanine moiety, respectively, were described. The in vitro cytotoxic activity by SRB assay on five cancer cell lines for sixteen tubulysins was evaluated. Among them, five analogues exhibited strong cytotoxic activities against five human cancer cell lines, including human breast carcinoma (MCF7), human colorectal adenocarcinoma (HT-29), HL-60, SW-480, human lung adenocarcinoma (A459). Interestingly, one analogue showed the strongest cytotoxicity on all five tested cell lines even much higher toxicity than the reference compound ellipticine.
