Abstract
In recent decades, annonaceous acetogenins have become highly studied plant secondary metabolites in terms of their isolation, structure elucidation, synthesis, biological evaluation, mechanism of action, and toxicity. The aim of the present contribution is to summarize chemical and biological reports published since 1997 on annonaceous acetogenins and synthetic acetogenin mimics. The compounds are considered biologically in terms of their cytotoxicity for cancer cell lines, neurotoxicity, pesticidal effects, and miscellaneous activities.

Abstract
Most Annonaceous acetogenins are characterized by between one and three THF ring(s) with one or two flanking hydroxyl group(s) in the center of a C32/34 fatty acid, and the terminal carboxylic acid is combined with a 2-propanol unit to form an alpha,beta-unsaturated gamma-lactone. While many studies have addressed the properties and synthesis of natural acetogenins due to their attractive biological activities and unique structural features, a number of analogues have also been described. This review covers the design, synthesis, and biological evaluation of acetogenin analogues.

Abstract
A typical Brazilian plant, araticum (Annona crassiflora Mart.), is widely used in humans as therapeutic medicine to treat several diseases such as diarrhea, rheumatism and syphilis. It contains acetogenins which present cytotoxic, antitumogenic, and antiparasitic properties. In this study, mutagenic, antimutagenic and cytotoxic effects of araticum leaves ethanolic extract were evaluated by micronucleus test in mice. To evaluate the mutagenic activity, animals were treated with ethanolic extract of araticum (EEA) using 10, 20, 50, 100 and 160 mg.kg-1. For all doses, micronucleated polychromatic erythrocytes (MNPCE) frequency was evaluated at 24, 48 and 72 hours after treatment. To evaluate the antimutagenic activity, animals were treated with 10, 20, 50 and 100 mg.kg-1 of EEA and 4 mg.kg-1 of MMC simultaneously. The frequency of MNPCE was evaluated 36 hours after exposure. Cytotoxicity was evaluated by the polychromatic and normochromatic erythrocytes ratio (PCE/NCE). In the mutagenicity assessment, all doses of EEA resulted in no significant increase of MNPCE (P > 0.05), compared to solvent- control group. Regarding administration time, no significant difference among three evaluation periods was observed (P > 0.05). Such results indicate that EEA did not exert mutagenic activity. Cytotoxicity was evident in doses of 50, 100 and 160 mg.kg-1 at 24 and 48 hours after exposure. Concerning antimutagenicity, except the 10 mg.kg-1 co-administered with 4 mg/kg of MMC, all doses reduced significantly the frequency of MNPCE compared to the positive control group (P < 0.05). These results, therefore, indicate an antimutagenic activity of the EEA. Cytotoxicity was significantly increased (P < 0.01) at 100 mg.kg-1 EEA doses co-administered with 4 mg.kg-1 of MMC.

Abstract
Acetogenins of Annonaceae, including squamocin (1), exert spectacular cytotoxicity and the most potent inhibition of NADH:ubiquinone oxidoreductase known so far. Cell death induced by these natural products was identified as apoptosis and was thought to be linked to alterations in mitochondrial function. Quinone-squamocin hybrid compounds were semisynthesized and evaluated for their pro-apoptotic properties with a screening method based on dissipation of the mitochondrial transmembrane potential (DeltaPsim). Herein, we report a short one-step synthesis of a squamocin carboxylic acid analogue. For the first time on a natural product, the radical decarboxylation and quinone addition reaction has enabled preparation of a library of squamocin-quinone hybrids and four other analogues. Squamoquinone, tenfold more potent than squamocin as an inducer of apoptosis, emerged as a promising compound, as it induces apoptosis through a mitochondrial caspase-dependent pathway.

Abstract
Squamocin is one of the annonaceous acetogenins and has been reported to have anticancer activity. Squamocin was found to inhibit the growth of K562 cells in a time- and dose-dependent manner. Cell cycle analysis showed G2/M phase arrest in K562 cells following 24 h exposure to squamocin. During the G2/M arrest, cyclin-dependent kinase inhibitors (CDKIs), p21 and p27 were increased in a dose-dependent manner. Analysis of the cell cycle regulatory proteins demonstrated that squamocin did not change the steady-state levels of Cdk2, Cdk4, cyclin A, cyclin B1, cyclin D3 and cyclin E, but decreased the protein levels of Cdk1 and Cdc25C. These results suggest that squamocin inhibits the proliferation of K562 cells via G2/M arrest in association with the induction of p21, p27 and the reduction of Cdk1 and Cdc25C kinase activities.

Abstract
A number of aminoacyl triesters of squamocin 1, a cytotoxic acetogenin isolated from the seeds of Annona reticulata, have been synthesized in two to three steps from protected (l)-aminoacids and squamocin 1 using standard coupling/deprotection procedures. These semisynthetic analogs were tested on submitochondrial particles (SMP) for their complex I inhibitory activities, and against KB 3-1 cells in vitro. All triesters derivatives exhibited a complete extinction of activity at the enzymatic level, correlated to a reduced though modulated cytotoxicity in comparison with squamocin 1. This activity can apparently be considered as a function of the amphipathy of the analogs, the more amphiphilic ones being the more cytotoxic.

Abstract
The presence of two hydroxy groups adjacent to the THF ring(s) is a common structural feature of natural acetogenins. To elucidate the role of each hydroxy group in the inhibitory action of acetogenins, we synthesized three acetogenin analogues which lack either or both of the hydroxy groups, and investigated their inhibitory activities with bovine heart mitochondrial complex I. Our results indicate that the presence of either of the two hydroxy groups sufficiently sustains a potent inhibitory effect.

Abstract
The acetogenins of Annonaceae are known by their potent cytotoxic activity. In fact, they are promising candidates as a new future generation of antitumoral drugs to fight against the current chemiotherapic resistant tumors. The main target enzyme of these compounds is complex I (NADH:ubiquinone oxidoreductase) of the mitochondrial respiratory chain, a key enzymatic complex of energy metabolism. In an attempt to characterize the relevant structural factor of the acetogenins that determines the inhibitory potency against this enzyme, we have prepared a series of bis-tetrahydrofuranic acetogenins with different functional groups along the alkyl chain. They comprise several oxo, hydroxylimino, mesylated, triazido, and acetylated derivatives from the head series compounds rolliniastatin-1, guanacone, and squamocin. Our results suggest a double binding point of acetogenins to the enzyme involving the alpha,alpha'-dihydroxylated tetrahydrofuranic system as well as the alkyl chain that links the terminal alpha, beta-unsaturated-gamma-methyl-gamma-lactone. The former mimics and competes with the ubiquinone substrate. The latter modulates the inhibitory potency following a complex outline in which multiple structural factors probably contribute to an appropriate conformation of the compound to penetrate inside complex I.

Abstract
Several glycosyl derivatives of squamocin (1) have been synthesized by glycosylation under Lewis acid catalysis with two different 1-O-acetyl sugars. Separation of these compounds has been achieved by HPLC and centrifugal partition chromatography (CPC). A detailed NMR, ESIMS, and LSIMS study allowed complete structural elucidations. The cytotoxic activity of the glycosyl derivatives was investigated and compared with that of squamocin and dihydrosquamocin against human epidermoid carcinoma cells (KB), African green monkey (Cercopithecus aethiops) kidney epithelial cells (VERO), and mouse lymphocytic leukemia cells (L1210). The antiproliferative effects of some derivatives were studied on cell cycles in mouse lymphocytic leukemia cells (L1210).
