Synthesis of novel 10,11-methylenedioxy-camptothecin glycoside derivatives and investigation of their anti-tumor effects in vivo

10,11-Methylenedioxy-camptothecin (FL118) is a novel camptothecin analogue that possesses exceptional antitumor efficacy in human tumor xenograft models. The aim of the current study was to develop novel 20-substituted FL118 derivatives coupled with glycosyl-succinic acid esters with improved antitumor efficacy. These FL118 glycoside derivatives were designed, synthesized and their cytotoxicity evaluated in three tumor cell lines (A-549, MDA-MB-231 and RM-1). All of the derivatives showed superior in vitro cytotoxic activity and were more potent than irinotecan in A549 and MDA-MB-231 cells. In mouse prostate cancer cells RM-1, 10,11-methylenedioxy-camptothecin rhamnoside 11b displayed significant activities with IC50 of 48.27 nM. Western blot analysis demonstrated that 11b inhibited survivin expression and induced cancer cells apoptosis. Further cell cycle analyses clearly showed 11b induced G2/M phase cell cycle arrest. Molecule docking studies suggested that the binding mode of 11b was different from that of the crystal complex of ligand topotecan in Top1/DNA. Importantly, 11b showed high in vivo antitumor efficacy in the RM-1 mouse model with transplantation of prostate cancer (TGI = 44.9%) at dose of 9 mg kg?1 without apparent toxicity.

Synthesis of glycosyl chlorides using catalytic Appel conditions

The stereoselective synthesis of glycosyl chlorides using catalytic Appel conditions is described. Good yields of alpha-glycosyl chlorides were obtained using a range of glycosyl hemiacetals, oxalyl chloride and 5 mol% Ph3PO. For 2-deoxysugars treatment of the corresponding hemiacetals with oxalyl chloride without phosphine oxide catalyst also gave good yields of glycosyl chloride. The method is operationaly simple and the 5 mol% phosphine oxide by-product can be removed easily. Alternatively a one-pot, multi-catalyst glycosylation can be carried out to transform the glycosyl hemiacetal directly to a glycoside.

Synthesis of cyclosal-(glycopyranosyl-6)-phosphates as activated sugar phosphates

The synthesis of cycloSal-masked glycopyranosyl phosphates demands suitably protected precursors. A highly regioselective strategy for the preparation of cycloSal-(1,2,3,4-tetra-O-acetylglycopyranosyl-6)-phosphates was developed. Intermediate introduction of the Fmoc-group allowed the isolation of the 1,2,3,4-tetra-O-acetyl glycopyranoses to be skipped, thus, no isomerization occurred. Glycopyranoses were first converted into the 6-O-TBDMS-1,2,3,4-tetra- O-acetyl derivatives then, in a one-pot reaction, the silyl ether was cleaved and the resulting 1,2,3,4-tetra-O-acetyl glycopyranoses were trapped with Fmoc-chloride. In this exchange of protecting groups no acetyl group migration occurred. The 6-O-Fmoc-protected intermediates were selectively converted into the cycloSal-masked glycopyranosyl phosphates in a one-pot reaction. Finally, the reactivity of these activated glycopyranosyl-6-phosphates was demonstrated in the synthesis of 1,6-diglycopyranosyl-phosphates. The preparation of 6-Fmoc-protected glycopyranoses succeeded with up to 83 % yield starting from the corresponding glycopyranoses. With this strategy, the migration of acetyl groups can be avoided and the acceptor-substituted cycloSal phosphate triesters were prepared regioselectively. These activated glycopyranosyl-6-phosphates can be used in coupling reactions with nucleophiles. Copyright

Design, synthesis and in vitro evaluation of d-glucose-based cationic glycolipids for gene delivery

A cationic lipid consists of a hydrophilic headgroup, backbone and hydrophobic tails which have an immense influence on the transfection efficiency of the lipid. In this paper, two novel series of cationic cyclic glycolipids with a quaternary ammonium headgroup and different-length hydrophobic tails (dodecyl, tetradecyl, hexadecyl) have been designed and synthesized for gene delivery. One contains lipids 1-3 with two hydrophobic alkyl chains linked to the glucose ring directly via an ether link. The other contains lipids 4-6 with two hydrophobic chains on the positively charged nitrogen atoms. All of the lipids were characterized for their ability to bind to DNA, size, zeta-potential, and toxicity. Atomic force microscopy showed that the lipids and DNA-lipid complexes were sphere-like forms. The lipids were used to transfer enhanced green fluorescent protein (EGFP-C3) to HEK293 cells without a helper lipid, the results indicated that lipids 4-6 have better transfection efficiency, in particular lipids 5-6 have similar or better efficiency, compared with the commercial transfection reagent lipofectamine 2000.

Natural product-like combinatorial libraries based on privileged structures. 1. General principles and solid-phase synthesis of benzopyrans

Herein we report a novel strategy for the design and construction of natural and natural product-like libraries based on the principle of privileged structures, a term originally introduced to describe structural motifs capable of interacting with a variety of unrelated molecular targets. The identification of such privileged structures in natural products is discussed, and subsequently the 2,2-dimethylbenzopyran moiety is selected as an inaugural template for the construction of natural product-like libraries via this strategy. Initially, a novel solid-phase synthesis of the benzopyran motif is developed employing a unique cycloloading strategy that relies on the use of a new, polystyrene-based selenenyl bromide resin. Once the loading, elaboration, and cleavage of these benzopyrans was established, this new solid-phase method was then thoroughly validated through the construction of six focused combinatorial libraries designed around natural and designed molecules of recent biological interest.
