Studying the conformations of the Annonaous acetogenins within liposomes made of dimyristoylphosphatidylcholine (DMPC) and on the basis of 1H NMR intermolecular nuclear Overhauser effects (NOEs), differential calorometric scanning data, and DMPC–Mn2+ peak-broadening studies, Shimada et al. found that the Annonaceous acetogenins, containing either mono-, adjacent bis-, or nonadjacent bis-THF ring moieties, have their THF ring moieties residing at the interfacial regions of the lipid membranes.43,44 It was concluded that the THF group-(s) serve as a hydrophilic anchor in the lipid membranes. It was also found that the position of the THF ring anchor along the acetogenin chain determines the depths of penetration of the lactone functional group within the lipid bilayer. Thus, the lactone ring, tethered to spacer moieties of different lengths, penetrates the lipid membrane to different depths, acts directly with the protein receptor site-(s), and adapts to the geometry of specific cell types.

Implementation of COMPASS (COMmon geometrical Pattern Search System) and molecular field fitting for all combinations of the stable conformations of each molecule, in this work led to several important conclusions. First, the inhibition mechanism of Annonaceous acetogenins was found to be noncompetitive against exogenous ubiquinones; this conclusion is not in agreement with the results of Friedrich et al.95 and Delgi Espositi et al.96 where Annonaceous acetogenins were concluded to bind competitively with respect to the ubiquinone at complex I. Second, while both rotenone and the Annonaceous acetogenins do bind noncompetitively against exogenous ubiquinone at complex I, they have different binding sites; however, most Annonaceous acetogenins (except rolliniastatin-2 and cherimolin-1) and rotenone were found to be mutually exclusive inhibitors.96,136 Third, stereochemistry surrounding the THF rings, surprisingly, seems to be much less important for activity at the enzyme level than in previous bioassays; this was corroborated by an exhaustive conformational space search analysis that indicated that the model compounds, with different stereochemical arrangements around the THF moieties, were in fairly good superimposition. Fourth, like the findings of González et al.122,137 and Gallardo et al.,138 proper length and flexibility of the alkyl spacer moiety, which links the THF and the α,β-unsaturated γ-lactone ring moieties, were essential for potent activity.45 Indeed, as Miyoshi et al. stated, if the THF rings serve as an anchor at the interface of the membrane, the stereochemical differences within the THF rings of the acetogenins should not make much difference in their bioactivity profiles.

(5) Neither the 4-OH group nor the 10-OH group is essential for activity. (6) Three hydroxyl groups, two flanking the THF ring(s) and another somewhere in the long hydrocarbon chain, provide both the optimal position and polarity needed for the most potent activity, and beyond the tetra-hydroxylated acetogenins the activity drops drastically.

In our recent work,[20,21] we showed that acetogenins, because of their potent ability to block ATP production, can selectively inhibit the growth of MDR tumors cells in vitro. A thorough examination of the acetogenins against in vivo models of multidrug resistance is now suggested. Using both wild-type and adriamycin-resistant human mammary adenocarcinoma cells in vitro (MCF-7/wt and MCF-7/Adr, respectively), Oberlies et al. observed that the MCF-7/Adr cells were more susceptible to acetogenin treatment and elicited a linear dose response curve. Alternatively, against the MCF-7/wt cells, a plateau near the IC50 value was observed (this is commonly seen with acetogenins). This observation led to the hypothesis that the acetogenins were cytotoxic to the MCF-7/Adr cells but more cytotoxic to the MCF-7/wt cells. For example, in contrast to adriamycin, vincristine, and vinblastine (Figures 3 and 4), bullatacin was effective at inhibiting the growth of the MDR MCF-7/Adr cells and exhibited a linear dose-response curve over a concentra-", "reading_order": 12 } ] }, { "page": 7, "items": [ { "page": 7, "type": "TEXT", "location": { "l": 53.76, "t": 765.6, "r": 70.8, "b": 756.96 }, "text": "510", "reading_order": 0 }, { "page": 7, "type": "FIGURE", "location": { "l": 53.28, "t": 744, "r": 294.48, "b": 561.12 }, "text": "", "reading_order": 1 }, { "page": 7, "type": "TEXT", "location": { "l": 142.08, "t": 564.72, "r": 234, "b": 556.8 }, "text": "log[concentration (μg/mL)]", "reading_order": 2 }, { "page": 7, "type": "TEXT", "location": { "l": 52.32, "t": 553.2, "r": 295.92, "b": 501.36 }, "text": "Figure 5.

This observation was examined further by analyzing the growth of both cell lines periodically over the 7 days of the assay (Figures 6 and 7). In the MDR MCF-7/Adr cells, bullatacin inhibited cell growth by varying amounts in a dose-dependent fashion, i.e., nearly zero cell growth at the most concentrated dose of 1.0 μg/mL vs nearly 100% cell growth at the least concentrated dose of 1.0 × 10-4 μg/mL (Figure 6).

No growth-regulation effects were caused by any of the compounds tested. Low resistance ratios (RRs) were obtained for most compounds (except chlorpyrifos) (Table 3). Low resistance ratio values for second instars ranged from Q9 to 22 with the natural acetogenins and from 1.0 to 38 with the synthetic compounds; the fifth instars ranged from Q2 to 3.9 with the natural acetogenins and from Q6 to 80 with the synthetic compounds (Table 3). Hydromethylnon, an electron-transport complex III inhibitor, not surprisingly, showed the lowest RR among the synthetic pesticides.[22] The high mortality observed with the low resistance ratios, shown in this study,[22] suggested an excellent potential for the use of Annonaceous acetogenins in baits against cockroaches, and it is predictable that such pesticide-resistance also includes ATP-dependent factors.", "reading_order": 13 }, { "page": 9, "type": "TEXT", "location": { "l": 51.36, "t": 186, "r": 296.4, "b": 33.12 }, "text": "These compounds are proven to induce emesis in pigs; this is a definite safety factor should someone ingest excessive amounts of these materials either intentionally or unintentionally; indeed, a fluidextract of paw paw seeds was once sold as an emetic by the Eli Lilly Co.

Further research is now necessary to develop refined pesticidal strategies for the inclusion of such highly effective and environmentally friendly formulations to control pests. To meet the demands of further in vitro and in vivo pharmacological evaluation, we especially encourage the synthesis of those selectively cytotoxic acetogenins that are rare in nature, e.g., squamotacin, which is specific for prostate tumor cells; synthetic targets can also include a wide diversity of analogues based on the SAR generalizations, as determined using the natural compounds, as mentioned above. The high potency, selectivity, wide chemical and biological diversity, and effectiveness of these compounds against resistance could well make them become the next class of useful natural antitumor and pesticidal agents.", "reading_order": 4 }, { "page": 10, "type": "TEXT", "location": { "l": 313.92, "t": 546.24, "r": 559.2, "b": 474.72 }, "text": "Acknowledgment.
