Phosphinic acid-based inhibitors of tubulin polyglutamylases.

ABSTRACT: Tubulin is subject to a reversible post-translational modification involving polyglutamylation and deglutamylation of glutamate residues in its C-terminal tail. This process plays key roles in regulating the function of microtubule associated proteins, neuronal development, and metastatic progression. This study describes the synthesis and testing of three phosphinic acid-based inhibitors that have been designed to inhibit both the glutamylating and deglutamylating enzymes. The compounds were tested against the polyglutamylase TTLL7 using tail peptides as substrates (100 ?M) and the most potent inhibitor displayed an IC?? value of 150 ?M. The incorporation of these compounds into tubulin C-terminal tail peptides may lead to more potent TTLL inhibitors.

Bis(aminomethyl)phosphinic Acid, a Highly Promising Scaffold for the Development of Bacterial Urease Inhibitors.

Project description:Inhibitors of bacterial ureases are considered to be promising compounds in the treatment of infections caused by Helicobacter pylori in the gastric tract and/or by urealytic bacteria (e.g., Proteus species) in the urinary tract. A new, extended transition state scaffold, bis(aminomethyl)phosphinic acid, was successfully explored for the construction of effective enzyme inhibitors. A reliable methodology for the synthesis of phosphinate analogues in a three-component Mannich-type reaction was elaborated. The obtained molecules were assayed against ureases purified from Sporosarcina pasteurii and Proteus mirabilis, and aminomethyl(N-n-hexylaminomethyl)phosphinic acid was found to be the most potent inhibitor, with a K i = 108 nM against the S. pasteurii enzyme.

Benz-yl(phen-yl)phosphinic acid.

Project description:The title compound, C(13)H(13)O(2)P, crystallized as enanti-omerically pure crystals; for the crystal measured, the P atom has R stereochemistry. The crystal structure displays O-H⋯O hydrogen bonding, which links individual mol-ecules related by a 2(1) screw axis parallel to the crystallographic a-axis direction into continuous chains.

Benz-yl(meth-yl)phosphinic acid.

Project description:The title compound, C(8)H(11)O(2)P, is a phosphinic compound with a tetra-coordinate penta-valent P atom. The phosphinic function plays a predominant role in the cohesion of the crystal structure, both by forming chains along the b axis via strong inter-molecular O-H⋯O hydrogen bonds and by cross-linking these chains perpendicularly via weak inter-molecular C-H⋯O hydrogen bonds, generating a two-dimensional network parallel to (001).

Ethane-1,2-diylbis(methyl-phosphinic acid).

Project description:In the title compound, C(4)H(12)O(4)P(2), there are two crystallographically independent half-mol-ecules in the asymmetric unit, both molecules lying on centres of symmetry. Each mol-ecule is connected on both sides to neighbouring mol-ecules via strong O-H⋯O hydrogen bonds. The -POOH groups accept and donate one hydrogen bond in interactions with the neighbouring -POOH group of the adjacent mol-ecule, to give one-dimensional chains along [10]. As each phosphinic acid group donates and accepts one hydrogen bond, the connection between the mol-ecules is best described by a ring motif which can be classified by the Etter symbol R(2) (2)(8).

Highly potent triazole-based tubulin polymerization inhibitors.

Project description:We describe the synthesis and biological evaluation of a series of tubulin polymerization inhibitors that contain the 1,2,4-triazole ring to retain the bioactive configuration afforded by the cis double bond in combretastatin A-4 (CA-4). Several of the subject compounds exhibited potent tubulin polymerization inhibitory activity as well as cytotoxicity against a variety of cancer cells including multi-drug-resistant (MDR) cancer cell lines. Attachment of the N-methyl-5-indolyl moiety to the 1,2,4-triazole core, as exemplified by compound 7, conferred optimal properties among this series. Computer docking and molecular simulations of 7 inside the colchicine binding site of tubulin enabled identification of residues most likely to interact strongly with these inhibitors and explain their potent anti-tubulin activity and cytotoxicity. It is hoped that results presented here will stimulate further examination of these substituted 1,2,4-triazoles as potential anti-cancer therapeutic agents.

Biosynthesis of phosphonic and phosphinic acid natural products.

Project description:Natural products containing carbon-phosphorus bonds (phosphonic and phosphinic acids) have found widespread use in medicine and agriculture. Recent years have seen a renewed interest in the biochemistry and biology of these compounds with the cloning of the biosynthetic gene clusters for several family members. This review discusses the commonalities and differences in the molecular logic that lie behind the biosynthesis of these compounds. The current knowledge regarding the metabolic pathways and enzymes involved in the production of a number of natural products, including the approved antibiotic fosfomycin, the widely used herbicide phosphinothricin (PT), and the clinical candidate for treatment of malaria FR-900098, is presented. Many of the enzymes involved in the biosynthesis of these compounds catalyze chemically and biologically unprecedented transformations, and a wealth of new biochemistry has been revealed through their study. These investigations have also suggested new strategies for natural product discovery.

Structural interrogation of benzosuberene-based inhibitors of tubulin polymerization.

Project description:The discovery of 3-methoxy-9-(30,40,50-trimethoxyphenyl)-6,7-dihydro-5H-benzo[7]annulen-4-ol (a benzosuberene-based analogue referred to as KGP18) was originally inspired by the natural products colchicine and combretastatin A-4 (CA4). The relative structural simplicity and ease of synthesis of KGP18, coupled with its potent biological activity as an inhibitor of tubulin polymerization and its cytotoxicity (in vitro) against human cancer cell lines, has resulted in studies focused on new analogue design and synthesis. Our goal was to probe the relationship of structure to function in this class of anticancer agents. A series of twenty-two new benzosuberene-based analogues of KGP18 was designed and synthesized. These compounds vary in their methoxylation pattern and separately incorporate trifluoromethyl groups around the pendant aryl ring for the evaluation of the effect of functional group modifications on the fused six-membered aromatic ring. In addition, the 8,9-saturated congener of KGP18 has been synthesized to assess the necessity of unsaturation at the carbon atom bearing the pendant aryl ring. Six of the molecules from this benzosuberene-series of compounds were active (IC50 < 5 lM) as inhibitors of tubulin polymerization while four analogues were comparable (IC50 approximately 1 lM) in their tubulin inhibitory activity to CA4 and KGP18. The potency of a bis-trifluoromethyl analogue 74 and the unsaturated KGP18 derivative 73 as inhibitors of tubulin assembly along with their moderate cytotoxicity suggested the potential utility of these compounds as vascular disrupting agents (VDAs) to selectively target microvessels feeding tumors. Accordingly, water-soluble and DMSO-soluble phosphate prodrug salts of each were synthesized for preliminary in vivo studies to assess their potential efficacy as VDAs.
