Shimazaki T, Iguchi T, Takahashi N, Sano Y, Nakamura K, Mimaki Y. Steroidal glycosides from Ornithogalum thyrsoides bulbs and their cytotoxicity toward HL-60 human promyelocytic leukemia cells and SBC-3 human small-cell lung cancer cells. PHYTOCHEMISTRY 2024; 219:113985. [PMID: 38237845 DOI: 10.1016/j.phytochem.2024.113985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 01/09/2024] [Accepted: 01/09/2024] [Indexed: 01/23/2024]
Abstract
Ornithogalum thyrsoides Jacq belongs to the Asparagaceae family and is cultivated for ornamental purposes. The authors have previously reported several cholestane- and spirostan-type steroidal glycosides from O. thyrsoides. Conventional TLC analysis of the methanolic bulb extract of O. thyrsoides suggested the presence of unprecedented compounds; therefore, a detailed phytochemical investigation of the extract was performed and 35 steroidal glycosides (1-35), including 21 previously undescribed ones (1-21) were collected. The structures of 1-21 were determined mainly by analyses of their 1H and 13C NMR spectra with the aid of two-dimensional NMR spectroscopy. The isolated compounds were classified into three distinct groups: furostan-type (1, 2, 8-12, and 22), spirostan-type (3-7 and 23-26), and cholestane-type (13-21 and 27-35). Although the C/D-ring junction of the steroidal skeleton is typically trans-oriented, except for some cardiotonic and pregnane-type steroidal derivatives, 7 possess a cis C/D-ring junction. This is the first reported instance of such a configuration in spirostan-type steroidal derivatives, marking it as a finding of significant interest. Compounds 1-35 were evaluated for cytotoxicity against HL-60 human promyelocytic leukemia cells and SBC-3 human small-cell lung cancer cells. Compounds 3-6, 9, 17-21, 23-25, and 30-35 demonstrated cytotoxicity in a dose-dependent manner with IC50 values ranging from 0.000086 to 18 μM and from 0.00014 to 37 μM toward HL-60 and SBC-3 cells, respectively. Compound 19, which is obtained in a good yield and shows relatively potent cytotoxicity among the undescribed compounds, induces apoptosis in HL-60 cells, accompanied by arresting the cell cycle of HL-60 cells at the G2/M phase. In contrast, 19 causes oxidative stress-associated necrosis in SBC-3 cells. The cytotoxic mechanism of 19 is different between HL-60 and SBC-3 cells.

Abstract
As the continuous scientific research, seven new 1-oxygenated cholestane glycosides named osaundersiosides 1 A - 1 G were isolated from an EtOH extract of the bulbs of Ornithogalum saundersiae. Their structures were deduced by means of spectroscopic data, chemical evidence and the results of hydrolytic cleavage. The cytotoxicity and anti-inflammatory effects of osaundersiosides 1 A - 1 G were evaluated, but none of them displayed significant activities. [Formula: see text].

Abstract
Eight undescribed cholestane glycosides named osaundersioside A-H, along with three previously known compounds named osaundersioside I-K were isolated from Ornithogalum saundersiae Baker bulbs (Asparagaceae). Their structures were elucidated by extensive spectroscopic analysis and chemical methods. All isolates were evaluated for their cytotoxic activity and inhibitory effects on lipopolysaccharide (LPS)-induced nitric oxide (NO) production. Osaundersioside C was thus determined to exhibit specific cytotoxicity towards MCF-7 cell line with an IC50 value of 0.20 μM, Osaundersioside H exhibited inhibitory effect on NO production in macrophages at the concentration of 10-5 M, with inhibition rate of 56.81%.

Structures and Biological Activities of Plant Glycosides: Cholestane Glycosides from Ornithogalum Saundersiae, O. Thyrsoides and Galtonia Candicans, and Their Cytotoxic and Antitumor Activities.

Abstract
Systematic phytochemical screening of higher pants using a cytotoxicity-guided fractionation procedure resulted in the isolation from the bulbs of Ornithogalum saundersiae (Liliaceae) an acylated cholestane diglycoside, 17α-hydroxy-16β-[(O-(2-O-p-methoxybenzoyl-β-D-xylopyranosyl)-(1→3)-2-O-acetyl-α-L-arabinopyranosyl)oxy]cholest-5-en-22-one, tentatively named OSW-1. In vitro cytotoxic and in vivo antitumor screening of OSW-1 revealed that it is a possible candidate as a novel anticancer agent. Furthermore, more than 20 OSW-1-related compounds were isolated, not only from the bulbs of O. saundersiae, but also from those of O. thyrsoides and Galtonia candicans, which are taxonomically related to O. saundersiae. In vitro cytotoxic evaluation of all the isolated compounds and their semi-synthetic analogues allowed the structure-activity relationships of the OSW-1 derivatives to be established. In addition, these three plants were found to produce a series of novel cholestane glycosides with a new rearranged side-chain moiety, 24(23→22)abeo-cholestane, some of which showed potent cytotoxic activity against HL-60 leukemia cells.

Abstract
Previous phytochemical studies of the bulbs of Ornithogalum saundersiae, an ornamental perennial plant native to South Africa, resulted in the isolation of 29 new cholestane glycosides, some of which were structurally unique and showed potent cytotoxic activity against cultured tumor cell lines. Therefore, we aimed to perform further phytochemical examinations of methanolic extracts obtained from Ornithogalum saundersiae bulbs, isolating 12 new cholestane rhamnosides (1-12) and seven known compounds (13-19). The structures of the new compounds (1-12) were identified via NMR-based structural characterization methods, and through a sequence of chemical transformations followed by spectroscopic and chromatographic analysis. The cytotoxic activity of the isolated compounds (1-19) and the derivatives (1a and 6a) against HL-60 human promyelocytic leukemia cells and A549 human lung adenocarcinoma cells was evaluated. Compounds 10-12, 16, and 17 showed cytotoxicity against both HL-60 and A549 cells. Compound 11 showed potent cytotoxicity with an IC50 value of 0.16 µM against HL-60 cells and induced apoptotic cell death via a mitochondrion-independent pathway.

Abstract
Transforming tigogenin, a steroidal sapogenin, to a 24(23→22)-abeo-cholestane, which is an unusual structural feature shared by the aglycons of saundersiosides and candicanoside A, is described. The spiroketal of tigogenin was unfolded and the resulting C22-ketone was subjected to Favorskii rearrangement mediated by PhI(OAc)2/KOH/MeOH to squeeze out the C22 from the side chain, thus reaching the 24(23→22)-abeo-cholestane structure.

Abstract
To minimize the cytotoxicity of shikonin and alkannin that arises through the generation of reactive oxygen species (ROS) and alkylation of the naphthazarin ring, two series of novel core-scaffold-modified shikonin and alkannin derivatives were designed. These derivatives, which differ in their configurational and positional isomerism (R-, S-, and 2- and 6-isomers) were synthesized in high enantiomeric excess (>99 % ee). The selectivity of the dimethylated derivatives was significantly higher than the parent shikonin in vitro, but some side effects were still observed in vivo. Surprisingly, the dimethylated diacetyl derivatives with poor anticancer activity in vitro showed tumor-inhibiting effects similar to paclitaxel without any toxicity in vivo. The anticancer activity of these derivatives is in agreement with their low ROS generation and alkylating capacity, emphasizing their potential as prodrugs. This strategy provides means to address the nonspecific cytotoxicity of naphthazarin analogues toward normal cells.

Abstract
Convergent block syntheses of 26-thio- and selenodioscin have been achieved by developing the highly stereoselective 1,2-trans glycosylations of chacotriosyl imidate without recourse to neighboring group assistance. Both thiodioscin and selenodioscin possess cytotoxic activities similar to dioscin, a natural spirostanol glycoside.

Abstract
The Hyacinthaceae (sensu APGII), with approximately 900 species in about 70 genera, can be divided into three main subfamilies, the Hyacinthoideae, the Urgineoideae and the Ornithogaloideae, with a small fourth subfamily the Oziroëoideae, restricted to South America. The plants included in this family have long been used in traditional medicine for a wide range of medicinal applications. This, together with some significant toxicity to livestock has led to the chemical composition of many of the species being investigated. The compounds found are, for the most part, subfamily-restricted, with homoisoflavanones and spirocyclic nortriterpenoids characterising the Hyacinthoideae, bufadienolides characterising the Urgineoideae, and cardenolides and steroidal glycosides characterising the Ornithogaloideae. The phytochemical profiles of 38 genera of the Hyacinthaceae will be discussed as well as any biological activity associated with both crude extracts and compounds isolated. The Hyacinthaceae of southern Africa were last reviewed in 2000 (T. S. Pohl, N. R. Crouch and D. A. Mulholland, Curr. Org. Chem., 2000, 4, 1287-1324; ref. 1); the current contribution considers the family at a global level.

Abstract
The crystal structure of a triterpene component of Wyethia mollis has been obtained and compared with the previously reported structure of the compound. The compound in the crystal structure, lanosta-8,24-dien-3-one, 16,23-epoxy-(16β, 23 R), (1), is different from the previously reported compound, but has identical NMR and mass spectrometric data. The revised structure contains a tetrahydropyran E ring, a structural moiety rare in steroid triterpenes.

Abstract
Solamargine, (25R)-3β-{O-α-L-rhamnopyranosyl-(1→2)-[O-α-L-rhamnopyranosyl-(1→4)]-β-D-glucopyranosyloxy}-22α-N-spirosol-5-ene, has been synthesized in 13 steps in a 10.5% overall yield starting from the naturally abundant diosgenin. Condensation of a partially protected glucopyranosyl donor with an oxaza-spiro moiety, which was formed in one-pot azido reduction, significantly improved the synthesis of desired molecule. The target compound exhibited good cytotoxic activities against tumor cells HeLa, A549, MCF-7, K562, HCT116, U87, and HepG2 with IC(50) ranging from 2.1 to 8.0 μM.

Abstract
A novel series of aminothiazonaphthalimides, A(1-2) and B(1-2), has been regioselectively synthesized. The linear compounds B(1-2) were evaluated to be far more active than their angular isomers A(1-2) in antitumor evaluation. The linear compounds C-F, derived from compound B(1), all showed highly efficient antitumor activities against A549 and P388 cell lines. Also, cytotoxicities of these four analogues against two tumor cells were highly dependent on the length of the side chains. The compound A(1) or B(1), with two methylene units in the side chain, was more cytotoxic than its corresponding homologue A(2) or B(2), with one more methylene unit.

Abstract
Several novel isoquino[4,5-bc]acridine derivatives have been designed and synthesized. Their DNA-binding, anti-tumor and DNA-photo-damaging properties were investigated. A4 exhibited the highest anti-tumor activities against both A 549 (human lung cancer cell) and P388 (murine leukemia cells). All these compounds were found to be more cytotoxic against P388 than against A549. Under 365-nm light irradiation, A3 damaged plasmid DNA pBR322 at <2 microM and cleaved DNA from form I to 100% form II by 50 microM. The mechanism studies revealed that A3 damaged DNA by electron transfer mechanism and singlet oxygen species.

Abstract
8-Oxo-8H-acenaphtho[1,2-b]pyrrole-9-carboxylic acid esters and derivatives were prepared and evaluated for cytotoxicity against A549 and P388 cell lines. Based on a novel chromophore precursor 8-oxo-8H-acenaphtho[1,2-b]pyrrol-9-carbonitrile 1, the very insoluble 1 was converted to more soluble esters 5 and a series of 3-amino derivatives from 5 were obtained by mild S(N)Ar(H) reaction between 5 and various amines. The biological evaluation indicated that methyl esters 5a are the most cytotoxic with IC(50) values of 0.45 and 0.80 microM (against A549 and P388, respectively) among the parent esters 5a-5f, but 3-amino derivatives 4b and 4c of 5f with bromine showed the highest activity (with IC(50) values of 0.019-0.60 microM) among the 3-amino derivatives.

Abstract
The novel DNA interactive isoquinolino[5,4-ab]phenazine derivatives were designed and synthesized. Their inhibitory abilities toward topoisomerase I, antitumor activities and DNA photo-cleaving abilities were examined. The substituents at peri sites of two phenazine N atoms played very important roles for all these biological activities. At a concentration of 100 microM, all these phenazine derivatives (but A2 and A6) exhibited an inhibitory activity toward topoisomerase I. A6 had efficient antitumor activities against both human lung cancer cell (A549) and murine leukemia cell (P388). A1, A5, and A6 exhibited antitumor activities selectively against P388. A2 was the most efficient DNA photocleaver, which had converted supercoiled DNA from form I to form II at <1 microM. Under anaerobic conditions, the electron transfer mechanism mainly contributed to DNA photo-induced cleavage, while under aerobic conditions, superoxide anion was also involved in this process.

Abstract
A series of novel antitumor and DNA photocleaving agents was designed and synthesized by fusing a (substituted) thiazole ring to the naphthalimide skeletons. C1, the most active compound against A549, was about 30-fold more cytotoxic than the compound amonafide. A1, the most active compound against P388, was about 6-fold more cytotoxic than amonafide. C2, the most efficient DNA intercalator, showed the strongest DNA photocleaving activity via superoxide anion produced under UV light at 360 nm.

Abstract
A series of methylthiazonaphthalimides was synthesized and quantitatively evaluated as efficient DNA intercalators, antitumor agents and DNA photocleavers. A(1) showed both efficient antitumor activities against cell lines of A549 and P388 with IC50 of 82.8 and 31 nM, respectively. A(3) was the strongest antitumor agent against A549 with the IC50 of 20.8 nM. A(2), the most efficient DNA intercalator, was found to be the strongest DNA photocleaver via superoxide anion. An explanation was given for the disaccord between antitumor and DNA photocleaving activities.

Abstract
Chlorogenin 3-O-beta-chacotrioside (1) and its 6alpha-O-acyl derivatives (2-6) were concisely synthesized. Introduction of a hydroxyl or acyloxy group onto the C-6 of the steroidal aglycone of dioscin decreased significantly the cytotoxicity of the parent saponin (dioscin).

Abstract
A new heterocyclic family of (2-(dimethylamino)ethyl)-2-substituted phenylnaphtho[2,1-d]thiazole-5-carboxamides modified from naphthalimides was designed, synthesized, and quantitatively evaluated as antitumor agents and photonucleases. All these compounds were found to be more cytotoxic against P388 than against A549. B(3) (m-NO(2)) was found to be the strongest inhibitor for P388 with IC(50) of 1.49 microM, while B(2) was the most cytotoxic compound against A549 with IC(50) of 12 microM. B(4) (p-CH(3)), the most efficient DNA photocleaver, showed detectable DNA cleavage at 0.5 microM and total cleavage from form I to 100% form II at 50 microM. The photocleaving mechanism was changed with the modification to be via superoxide anion and radical.

Abstract
Four analogs of OSW-1 (1-4) with modified side chains on the steroidal skeleton were synthesized following modification of our previous route for the total synthesis of OSW-1. Testing of the analogs against growth of tumor cells demonstrated that the 22-one function and the full length of the side chain of OSW-1 were not required for the antitumor action of OSW-1.
