  Synthesis of prenylated benzaldehydes and their use in the synthesis of analogues of licochalcone A

  摘要：

  In this paper, a general applicable synthesis of prenylated aromatic compounds exemplified by prenylated benzaldehydes starting from readily available acetophenones is described. The synthesized benzaldehydes are used to prepare a number of novel analogues of Licochalcone A, a known antibacterial compound, and for the exploration of the pharmacophoric elements that are essential for the antibacterial activity. It is shown that the hydroxyl group in the A ring is essential for the activity and that the hydroxyl group in the B ring has no influence on the antibacterial effect of Licochalcone A. Furthermore, it is shown that the prenyl group at the position 5 of the B ring also has a dominating influence on the activity. This aliphatic group can be replaced by other lipophilic long chained substituents in order to maintain the activity.

• Inhibitory effect of chalcones and their derivatives from Glycyrrhiza inflata on protein tyrosine phosphatase 1B

  Compounds (1-6) isolated from the CH2Cl2 extract of Glycyrrhiza inflata and semisynthetic licochalcone A derivatives (7-14) were evaluated for their protein tyrosine phosphatase 1B (PTP1B) inhibitory activities. Licochalcones A (4) and E (6), each with an allyl group at position 5 in the B ring exhibited significant inhibitory effects. Licochalcone A derivative 7, the most potent among the series, had an IC50 value of 11.7 +/- 2.0 mu M, ca. twofold better than that of licochalcone A (4). (C) 2009 Elsevier Ltd. All rights reserved.

  (EN) Aromatic compounds, or prodrugs thereof, which contain an alkylating site and which are capable of alkylating the thiol group in N-acetyl-L-cysteine, in particular bis-aromatic $g(a),$g(b)-unsaturated ketones, are used for the preparation of pharmaceutical compositions or medicated feed, food or drinking water for the treatment or prophylaxis of diseases caused by microorganisms or parasites, in particular protozoa such as $i(Leishmania, Trypanosoma, Toxoplasma, Plasmodium, Pneumocystis, Babesia) and $i(Theileria), intestinal protozoa such as $i(Trichomonas) and $i(Ciardia; Coccidia) such as $i(Eimeria, Isospora, Cryptosporidium; Cappilaria, Microsporidium, Sarcocystis, Trichodina, Trichodinella, Dacthylogurus, Pseudodacthylogurus, Acantocephalus, Ichthylophtherius, Botrecephalus); and intracellular bacteria, in particular $i(Mycobacterium, Legionella) species, $i(Listeria) and $i(Salmonella). Preferred compounds have the formula (II): Xm-Ph-C(O)-CH=CH-Ph-Yn, wherein each phenyl group (Ph) may be mono- or polysubstituted; X and Y designate ARH or AZ, wherein A is O, S, NH or N(C1-6alkyl), RH designates aliphatic hydrocarbyl, and Z is H or a masking group which is decomposed to liberate AH; m is 0, 1 or 2, and n is 0, 1, 2 or 3, whereby, when m is 2, then the two X are the same or different, and when n is 2 or 3, then the two or three Y are the same or different, with the proviso that n and m are not both 0. As examples of such compounds, chalcones, e.g. licochalcone A (obtainable i.a. from batches of Chinese licorice root of Glycyrrhiza species, e.g. $i(G. uralensis) or $i(G. inflata)) as well as hydroxy, alk(en)yl, and/or alk(en)yloxy analogues thereof are active $i(in vitro) and/or $i(in vivo) against i.a. $i(L. major) and $i(P. falciparum).(FR) Composés aromatiques, ou pro-médicaments issus de ces composés, comportant un site d'alkylation et aptes à réaliser l'alkylation du groupe thiol dans la N-acétyl-L-cystéine, en particulier $g(a),$g(b)-cétones insaturées bisaromatiques, utilisés pour la production de préparations pharmaceutiques ou d'aliments médicamenteux, d'aliments ou d'eaux de boisson pour le traitement ou la prophylaxie de maladies causées par des microorganismes ou des parasites, en particulier par des protozoaires tels que $i(Leishmania, Trypanosoma, Toxoplasma, Plasmodium, Pneumocystis, Babesia) et $i(Theileria), par des protozoaires intestinaux tels que les $i(Trichomonas) et $i(Ciardia; Coccidia) tels que $i(Emeria, Isospora, Cryptosporidium, Cappilaria, Microsporidium, Sarcocystis, Trichodina, Trichodinella, Dacthylogurus, Pseudodacthylogurus, Acantocephalus, Ichthylophtherius, Botrecephalus); et des bactéries intracellulaires, notamment les espèces $i(Mycobacterium, Legionella, Listeria) et $i(Salmonella). Les composés préférés présentent la formule (II): Xm-Ph-C(O)-CH=CH-Ph-Yn, dans laquelle chacun des groupes phényle (pH) peut être mono ou polysubstitué; X et Y désignent ARH ou AZ, dans lequel A est O, S, NH ou N(C1-6alkyle), RH désigne un radical hydrocarbyle aliphatique, et Z est H ou un groupe écran qui est décomposé pour libérer AH; m est 0, 1 ou 2 et n est 0, 1, 2 ou 3, de telle sorte que, quand m est égal à 2, les deux X sont identiques ou différents, et lorsque n est égal à 2 ou 3, les deux ou trois Y sont identiques ou différents, pourvu que n et m ne soient pas tous les deux égaux à 0. Comme exemples de ces composés, on citera les chalcones, par exemple licochalcone A (pouvant être obtenu notamment à partir de racines de réglisse de l'espèce Glycyrrhiza, par exemple $i(G. uralensis) ou $i(G. inflata)) ainsi que leurs analogues hydroxy, alk(én)yle et/ou alk(én)yloxy, actifs $i(in vitro) et/ou $i(in vivo) contre notamment $i(L. major) et $i(P. falciparum).
