- Copper(II)-catalyzed hydroxylation of aryl halides using glycolic acid as a ligand
-
Copper(II)-catalyzed hydroxylation of aryl halides has been developed to afford functionalized phenols. The protocol utilizes the reagent combination of Cu(OH)2, glycolic acid, and NaOH in aqueous DMSO, all of which are cheap, readily available, and easily removable after the reaction. A broad range of aryl iodides and activated aryl bromides were transformed into the corresponding phenols in excellent yields. Moreover, it has been shown that C-O(alkyl)-coupled product, instead of phenol, can be predominantly formed under similar reaction conditions.

- Antimalarial activity enhancement in hydroxymethylcarbonyl (HMC) isostere-based dipeptidomimetics targeting malarial aspartic protease plasmepsin
-
Plasmepsin (Plm) is a potential target for new antimalarial drugs, but most reported Plm inhibitors have relatively low antimalarial activities. We synthesized a series of dipeptide-type HIV protease inhibitors, which contain an allophenylnorstatine-dimethylthioproline scaffold to exhibit potent inhibitory activities against Plm II. Their activities against Plasmodium falciparum in the infected erythrocyte assay were largely different from those against the target enzyme. To improve the antimalarial activity of peptidomimetic Plm inhibitors, we attached substituents on a structure of the highly potent Plm inhibitor KNI-10006. Among the derivatives, we identified alkylamino compounds such as 44 (KNI-10283) and 47 (KNI-10538) with more than 15-fold enhanced antimalarial activity, to the sub-micromolar level, maintaining their potent Plm II inhibitory activity and low cytotoxicity. These results suggest that auxiliary substituents on a specific basic group contribute to deliver the inhibitors to the target Plm.

- Synthesis and anti-inflammatory activity of 2-aryloxy methyl oxazolines
-
A series of potential biologically active 2-aryloxy methyl oxazolines 3a-n have been synthesized from substituted hydroxybenzenes 1a-n with good chemical yield. The compounds 3a-n were screened for their anti-inflammatory, ulcerogenic, cyclooxygenase activities and also for their acute toxicity. The potency of the compounds was compared with that of the standard drugs, aspirin and phenyl butazone. The outcome indicates that compounds 3b (48.2%), 3h (48.5%) and 3l (46.5%) offered significant anti-inflammatory activity with low ulcerogenic activity than the standard drugs.

- A convenient preparation of N-alkyl and N-arylamines by smiles rearrangement - Synthesis of analogues of diclofenac
-
Smiles rearrangement of substituted aryloxyacetamides in which oxygen and nitrogen are separated by COCH2 group has been successful even when the aryloxy ring carries weak or no electron withdrawing group. Earlier reports of such reactions involved either strong electron withdrawing groups or a special catalyst. The diphenylamines thus obtained gave analogues of diclofenac in only one case.

The aryloxyacetic acid are prepared by the reaction of substituted phenols with chloroacetic acid in the presence of aq. sodium hydroxide. The antimicrobial activity of these compounds have been assayed against various Gram+ve, Gram-ve bacteria and fungi. The constitution of the products have been elucidated by IR, 1H NMR and mass spectral data and elemental analyses.

- Syntheses of HIV-protease inhibitors having a peptide moiety which binds to GP120
-
Some HIV-protease inhibitor derivatives having an N- carbomethoxycarbonyl-prolyl-phenylalanine benzyl ester (CPF) moiety as a binding site to gp120 were designed and synthesized. Almost all the compounds bearing CPF on the phenoxyacetyl group showed protease-inhibitory activity. Compounds 25a and 25b, which have the CPF moiety at the ortho- and meta- positions of the phenoxyacetyl group, respectively, had anti-HIV activity, although the others showed only protease-inhibitory activity. These results suggest that 25b binds to gp120 and inhibits HIV protease.

- Synthesis of dipeptide-type human immunodeficiency virus (HIV) protease inhibitors with a binding unit to GP120
-
Some dipeptide-type human immunodeficiency virus (HIV) protease inhibitors derived from KNI-102, with a N-carbomethoxycarbonylprolyl- phenylalanine benzyl ester (CPF) moiety as a binding site to gp120, were synthesized. Compounds 11a showed 7 - 100 times higher HIV protease- inhibitory activity (11a; IC50 = 0.90 μg/ml, 1.1 μM) than the standard compound 3 or 4 (3; IC50 = 3.7 μg/ml, 7.7 μM, 4; IC50 = 75 μg/ml, 155 μM). Generally, the compounds substituted at the o-position of the phenoxyacetyl group 7a, 11a, 16a and 21a showed several times higher inhibitory activity than 3.

- Discovery of 1,5-benzodiazepines with peripheral cholecystokinin (CCK-A) receptor agonist activity (II): Optimization of the C3 amino substituent
-
Analogs of the previously reported 1,5-benzodiazepine peripheral cholecystokinin (CCK-A) receptor agonist 1 were prepared which explore substitution and/or replacement of the C-3 phenyl urea moiety. Agonist efficacy on the isolated guinea pig gallbladder (GPGB) was retained with a variety of substituted ureas and amide analogs. Three compounds were identified which were orally active in the mouse gallbladder emptying assay (MGBE). The 2-indolamide (52) and N-(carboxymethyl)-2-indolamide (54) derivatives had improved affinity for the human CCK-A receptor but reduced agonist efficacy on the GPGB. Neither indolamide was orally active in a rat feeding assay. In contrast, the (3-carboxyphenyl)urea derivative (29, GW7854) had moderately increased affinity for the human CCK-B receptor but was a potent full agonist on the GPGB and was orally active in both the MGBE and rat feeding assays. GW7854 was a full agonist (EC50 = 60 nM) for calcium mobilization on CHO K1 cells expressing hCCK-A receptors and a potent antagonist of CCK-8 (pA2 = 9.1) on CHO K1 cells expressing hCCK-B receptors. GW7854 is a potent mixed CCK-A agonist/CCK-B antagonist which is orally active in two in vivo models of CCK-A-mediated agonist activity.
