Synthesis of fluorescein derivatives containing metal-coordinating heterocycles
Clark, Matthew A.,Hilderbrand, Scott A.,Lippard, Stephen J.
, p. 7129 - 7131 (2004)
Fluorescein derivatives that contain Lewis basic heterocycles have been synthesized by concise reaction sequences. The preparation of these compounds proceeds by functionalization of an electron-rich aromatic precursor and subsequent condensation to form the fluorophore. These compounds are envisioned as components of metal-based sensors.

, p. 1732 - 1737 (2016/07/27)
The compound class of 1H-pyrazolo[3,4-d]pyrimidines was identified using HTS as very potent inhibitors of facilitated glucose transporter 1 (GLUT1). Extensive structure–activity relationship studies (SAR) of each ring system of the molecular framework was established revealing essential structural motives (i.e., ortho-methoxy substituted benzene, piperazine and pyrimidine). The selectivity against GLUT2 was excellent and initial in vitro and in vivo pharmacokinetic (PK) studies are encouraging.

Whole-cell screening of 20,000 drug-like small molecules led to the identification of nitrofuranyl methylpiperazines as potent anti-TB agents. In the present study, validation followed by medicinal chemistry has been used to explore the structure-activity relationship. Ten compounds demonstrated potent MIC in the range of 0.17-0.0072 μM against H37Rv Mycobacterium tuberculosis (MTB) and were further investigated against nonreplicating and resistant (RifR and MDR) strains of MTB. These compounds were also tested for cytotoxicity. Among the 10 tested compounds, five showed submicromolar to nanomolar potency against nonreplicating and resistant (RifR and MDR) strains of MTB along with a good safety index. Based on their overall in vitro profiles, the solubility and pharmacokinetic properties of five potent compounds were studied, and two analogues, 14f and 16g, were found to have comparatively better solubility than others tested and acceptable pharmacokinetic properties. This study presents the rediscovery of a nitrofuranyl class of compounds with improved aqueous solubility and acceptable oral PK properties, opening a new direction for further development.

This report describes the discovery that 1-substituted 4-(3-hydroxyphenyl) piperazines are pure opioid receptor antagonists. Compounds in this new series include N-phenylpropyl (3S)-3-methyl-4-(3-hydroxyphenyl)piperazine and (3R)-3-methyl-4-(3-hydroxyphenyl)piperazine, both of which display low nanomolar potencies at μ, δ, and κ receptors and pure antagonist properties in a [35S]GTPγS assay.

Scope and limitations of Pd2(dba)3/P(i-BuNCH 2CH2)3N-catalyzed Buchwald-Hartwig amination reactions of aryl chlorides
Urgaonkar, Sameer,Verkade, John G.
, p. 9135 - 9142 (2007/10/03)
Proazaphosphatrane ligands in combination with Pd2(dba) 3 generate highly active catalysts for Buchwald-Hartwig amination of aryl chlorides. In particular, commercially available P(i-BuNCH 2-CH2)3N is a highly general and efficient ligand, allowing the coupling of an electronically diverse set of aryl chlorides, including chloropyridines, with a wide variety of amines using 1 mol % of Pd at 100 °C. Either a 1:1 or 2:1 ratio of ligand to Pd was found to be effective. This catalyst system performs exceptionally well for sterically hindered substrates, even with only 0.25 mol % of Pd. It is shown that NaOH can also be used as the base (instead of NaO-t-Bu) allowing functionalized substrates to participate in these reactions.
