Total synthesis and stereochemical reassignment of tasiamide B

The first total synthesis of tasiamide B, an octapeptide bearing 4-amino-3-hydroxy-5-phenylpentanoic acid unit isolated from the marine cyanobacteria Symploca sp. is described. A simple and efficient way was found to avoid the pyroglutamylation of Nalpha-Me-Gln and led to a reassignment of the Nalpha-Me-L-Phe of tasiamide B to be N alpha-Me-D-Phe, which was also supported by 1D and 2D NMR.

5-Lipoxygenase-activating protein inhibitors. Part 2: 3-{5-((S)-1-Acetyl-2,3-dihydro-1H-indol-2-ylmethoxy)-3-tert-butylsulfanyl-1-[4-(5-methoxy-pyrimidin-2-yl)-benzyl]-1H-indol-2-yl}-2,2-dimethyl-propionic acid (AM679)-A potent FLAP inhibitor

A series of potent 5-lipoxygenase-activating protein (FLAP) inhibitors are herein described. SAR studies focused on the discovery of novel alicyclic moieties appended to an indole core to optimize potency, physical properties and off-target activities. Subsequent SAR on the N-benzyl substituent of the indole led to the discovery of compound 39 (AM679) which showed potent inhibition of leukotrienes in human blood and in a rodent bronchoalvelolar lavage (BAL) challenge model.

Development of high-affinity 5-HT3 receptor antagonists. Structure- affinity relationships of novel 1,7-annelated indole derivatives. 1

On the basis of the structures of ondansetron and GR 65,630, its ring- opened C-linked methylimidazole analogue, novel 1,7-annelated indole derivatives were synthesized as potential 5-HT3 antagonists. Receptor binding studies show that all compounds display a high affinity for the 5- HT3 receptors. In both series annelation results in compounds being 7 and 4 times more potent than the references ondansetron and GR 65,630, respectively. Similar to ondansetron, the 1,7-annelated indoles show little stereoselectivity. The (-)-isomers are only slightly more potent than the (+)-isomers. The receptor binding profile of l-10-[(2-methyl-1H-imidazol-1- yl)methyl]-5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazol-11-one hydrochloride (24b) (INN cilansetron) shows that the compound displays, besides a high affinity for 5-HT3 receptors (K(i) = 0.19 nM), a weak affinity for sigma-receptors (K(i) = 340 nM), muscarine M1 receptors (K(i) = 910 nM), and 5-HT4 receptors (K(i) = 960 nM) and no affinity (K(i) ? 5000 nM) for all the other receptor types tested (n = 37). The new compounds fit the proposed necessary chemical template for binding: a heteroaromatic ring system, a coplanar carbonyl group, and a nitrogen center at well-defined distances. The enhanced potency of the annelated 1,7-indole derivatives indicates that the extra ring provides a favorable hydrophobic area for interaction with the 5-HT3 receptor site. In vivo cilansetron is more potent and induces less central side effects than ondansetron. At present cilansetron is in clinical trials.

Zinc-Catalyzed Hydroxyl-Directed Regioselective Ring Opening of Aziridines in SN2 Reaction Pathway

In this protocol, a zinc-catalyzed catalytic regioselective ring opening of electronically and sterically unbiased 2,3-aziridinyl alcohols has been accomplished. The directing effect of the hydroxyl moiety enables the selective nucleophilic attack to the C-3 position of 2,3-aziridinyl alcohols with various aromatic amines and thiophenols as nucleophiles. This operationally simple reaction provides convenient access to a variety of amino alcohols and hydroxyl sulfides in excellent regiocontrol. Moreover, simple derivatization of the ring opening product establishes a general strategy to approach internal vicinal diamines in regioselective and diastereomerically pure form.

Synthesis and biological evaluation of novel pyridazinone-based alpha4 integrin receptor antagonists

A novel series of pyridazinone-functionalized phenylalanine analogues was prepared and evaluated for inhibition of cellular adhesion mediated by alpha4beta1/VCAM-1 and alpha4beta 7MAdCAM-1 interactions. Concise syntheses were developed and applied for exploration of structure-activity relationships pertaining to the pyridazinone ring as well as the N-acyl phenylalanine scaffold. Potent dual antagonists of alpha4beta1 and alpha 4beta7 were generated from an amide subseries; antagonists selective for alpha4beta7 were identified from urea and carbamate-based subseries. The pharmacokinetic properties of selected members of the series have been determined in rats and demonstrate that the use of ester prodrugs and alterations to the amide linkage can lead to improved oral bioavailability in this series. An alpha4beta 7-selective member of the carbamate subseries (36c), upon oral admininstration, demonstrated in vivo efficacy in the mouse DSS colitis model.

Antimicrobial and antioxidant evaluation of some novel synthesized pyridazinone derivatives

This study presents the synthesis and spectral analysis of novel pyridazinone derivatives. Cyclization reaction of mucochloric acid and semicarbazide hydrochloride in the presence of aqueous ethanol afforded 4,5-dichloro-2Hpyridazin- 3-one (1). Novel compounds were synthesized by treating the 4,5-dichloro-2H-pyridazin-3-one (1) with substituted aldehyde and amine derivatives. All synthesized compounds were screened for their in vitro antibacterial, antifungal activities by using the agar cup plate method. The newly synthesized compounds showed antimicrobial activity against all the strains. Compounds 3b and 3c showed very good antifungal activity against candida albicans and Aspergillus niger (minimal inhibitory concentration [MIC] = 12.5 mug/mL). Some compounds showed good activity against Gram (+ve) bacteria and Gram (-ve) bacteria. Antioxidant study was done by using DPPH fee radical scavenging activity. Antioxidant activity assay showed that compound 3b had highest scavenger activity.
