Abstract
Based on the known isatin-based fatty acid amide hydrolase (FAAH) inhibitor BSS-7, we designed and synthesized two small sets (6-13 and 17-20) of N-1 and C-3 substituted isatin derivatives and evaluated them for their in vitro FAAH inhibition properties. The lead simplification by modification of bulky aryl moiety at N-1 with a flexible allyl group produced a nanomolar (IC50 = 6.7 nM, Ki = 5 nM) inhibitor 11 (Z)-3-((1H-benzo[d]imidazol-2-yl)imino)-1-allylindolin-2-one which exhibited a reversible and competitive FAAH inhibition with 1500 times more potency to BSS-7 (1.49 ± 0.03 µM). The lead compound 11 also showed a high blood-brain permeability and a significant antioxidant profile with no neurotoxicity. Docking results suggested that the inhibitor molecules occupied the active site of FAAH and offered optimal binding interactions. A molecular dynamics simulation study ascertained the stability of the lead inhibitor 11-FAAH complex. In silico ADMET profiling studies unveiled that compound 11 possesses good drug-like properties and merits further evaluation.Communicated by Ramaswamy H. Sarma.

Abstract
The present study reports an asymmetric organocascade reaction of oxindole-derived alkenes with 3-bromo-1-nitropropane efficiently catalyzed by the bifunctional catalyst. Spirooxindole-fused cyclopentanes were produced in moderate-to-good isolated yields (15-69%) with excellent stereochemical outcomes. The synthetic utility of the protocol was exemplified on a set of additional transformations of the corresponding spirooxindole compounds.

Abstract
Writing scientific articles is immensely rewarding but challenging. This Perspective provides the medicinal chemist with background and advice on the art and process of writing manuscripts and complements the instructions to authors provided by journals. Included are many tips that we wish we had known when we first started writing. Bibliometric data from seven medicinal chemistry journals between 2000 and 2019 are collated including Bioorganic and Medicinal Chemistry Letters and the Journal of Medicinal Chemistry. Although the overall number of articles has doubled, the output from 23 large pharma companies in the past decade has dropped significantly. Commentary is given on the entire process of writing original scientific articles, opinion articles, and reviews. Examples from our own papers and experience are shared including what typically motivates the writer, challenges commonly encountered, and how we find time to write. Finally, the benefits derived from much wider publishing of industrial medicinal chemistry are described.

Abstract
We pursued a structure-guided approach toward the development of improved dihydroorotate dehydrogenase (DHODH) inhibitors with the goal of forming new interactions between DHODH and the brequinar class of inhibitors. Two potential residues, T63 and Y356, suitable for novel H-bonding interactions, were identified in the brequinar-binding pocket. Analogues were designed to maintain the essential pharmacophore and form new electrostatic interactions through strategically positioned H-bond accepting groups. This effort led to the discovery of potent quinoline-based analogues 41 (DHODH IC50 = 9.71 ± 1.4 nM) and 43 (DHODH IC50 = 26.2 ± 1.8 nM). A cocrystal structure between 43 and DHODH depicts a novel water mediated H-bond interaction with T63. Additional optimization led to the 1,7-naphthyridine 46 (DHODH IC50 = 28.3 ± 3.3 nM) that forms a novel H-bond with Y356. Importantly, compound 41 possesses significant oral bioavailability ( F = 56%) and an elimination t1/2 = 2.78 h (PO dosing). In conclusion, the data supports further preclinical studies of our lead compounds toward selection of a candidate for early-stage clinical development.

Abstract
Previously, we reported the discovery of PSI-697 (1a), a C-2 benzyl substituted quinoline salicylic acid-based P-selectin inhibitor. It is active in a variety of animal models of cardiovascular disease. Compound 1a has also been shown to be well tolerated and safe in healthy volunteers at doses of up to 1200 mg in a phase 1 single ascending dose study. However, its oral bioavailability was low. Our goal was to identify a back up compound with equal potency, increased solubility, and increased exposure. We expanded our structure-activity studies in this series by branching at the alpha position of the C-2 benzyl side chain and through modification of substituents on the carboxylic A-ring of the quinoline. This resulted in discovery of PSI-421 with marked improvement in aqueous solubility and pharmacokinetic properties. This compound has shown oral efficacy in animal models of arterial and venous injury and was selected as a preclinical development compound for potential treatment of such diseases as atherosclerosis and deep vein thrombosis.

Abstract
Syntheses and structure-antiproliferative relationship for oxyphenisatin analogues are described. The cell proliferation data showed that the presence of substituents (especially F, Cl, Me, CF(3), and OMe) in the 6- and 7-position of oxyphenisatin markedly enhanced the potency in the MDA-468 cell line without affecting the MDA-231 cell line. The best compounds from this series showed low nanomolar antiproliferative activity towards the MDA-468 cell line and a 1000-fold selectivity over the MDA-231 cell line.

Abstract
In our endeavor to design and synthesize novel anticancer agents, a new series of indoloquinazoline compounds were prepared and tested initially for anticancer activity in vitro against a panel of human cancer cell lines. Most of these compounds exhibited cytotoxic activity in in vitro screens. Compounds were selected and further evaluated using a modified Hollow Fiber Assay for their preliminary in vivo activity against 12 cell lines implanted in the subcutaneous and intraperitoneal compartments in mice. The results indicate that these compounds may constitute a new class of anticancer agents.

Abstract
A series of 3-aryloxindole derivatives were synthesized and evaluated as activators of the cloned maxi-K channel mSlo expressed in Xenopus laevis oocytes using electrophysiological methods. The most promising maxi-K openers to emerge from this study were (+/-)-3-(5-chloro-2-hydroxyphenyl)-1,3-dihydro-3-hydroxy-6-(trifluoromethyl)-2H-indol-2-one ((+/-)-8c) and its 3-des-hydroxy analogue (+/-)-11b. The individual enantiomers of (+/-)-8c were synthesized, and the maxi-K channel-opening properties were shown to depend on the absolute configuration of the single stereogenic center with the efficacy of (-)-8c superior to that of both (+)-8c and the racemic mixture when evaluated at a concentration of 20 microM. Racemic 11b exhibited greater efficacy than either the racemic 8c or the more active enantiomer in the electrophysiological evaluation. In vitro metabolic stability studies conducted with (+/-)-8c and (+/-)-11b in rat liver S9 microsomal fractions revealed significant oxidative degradation with two hydroxylated metabolites observed by liquid chromatography/mass spectrometry for each compound in addition to the production of 8c from 11b. The pharmacokinetic properties of (+/-)-8c and (+/-)-11b were determined in rats as a prelude to evaluation in a rat model of stroke that involved permanent occlusion of the middle cerebral artery (MCAO model). In the MCAO model, conducted in the spontaneously hypertensive rat, the more polar 3-hydroxy derivative (+/-)-8c did not demonstrate a significant reduction in cortical infarct volume when administered intravenously at doses ranging from 0.1 to 10 mg/kg as a single bolus 2 h after middle cerebral artery occlusion when compared to vehicle-treated controls. In contrast, intravenous administration of (+/-)-11b at a dose of 0.03 mg/kg was found to reduce the measured cortical infarct volume by approximately 18% when compared to vehicle-treated control animals. Intraperitoneal administration of (+/-)-11b at a dose of 10 mg/kg 2 h following artery occlusion was shown to reduce infarct volume by 26% when compared to vehicle-treated controls. To further probe the effects of compounds (+/-)-8c and (+/-)-11b on neurotransmitter release in vitro, both compounds were examined for their ability to reduce electrically stimulated [3H]-glutamate release from rat hippocampal slices that had been preloaded with [3H]-glutamate. Only (+/-)-11b was able to demonstrate a significant inhibition [3H]-glutamate release in this assay at a concentration of 20 microM, providing concordance with the profile of these compounds in the MCAO model. Although (+/-)-11b showed some promise as a potential developmental candidate for the treatment of the sequelae of stroke based on its efficacy in the rat MCAO model, the pharmacokinetic profile of this compound was considered to be less than optimal and was not pursued in favor of derivatives with enhanced metabolic stability.

Abstract
Two closely related classes of oxindole-based compounds, 1H-indole-2,3-dione 3-phenylhydrazones and 3-(anilinomethylene)-1,3-dihydro-2H-indol-2-ones, were shown to potently inhibit cyclin-dependent kinase 2 (CDK2). The initial lead compound was prepared as a homologue of the 3-benzylidene-1,3-dihydro-2H-indol-2-one class of kinase inhibitor. Crystallographic analysis of the lead compound bound to CDK2 provided the basis for analogue design. A semiautomated method of ligand docking was used to select compounds for synthesis, and a number of compounds with low nanomolar inhibitory activity versus CDK2 were identified. Enzyme binding determinants for several analogues were evaluated by X-ray crystallography. Compounds in this series inhibited CDK2 with a potency approximately 10-fold greater than that for CDK1. Members of this class of inhibitor cause an arrest of the cell cycle and have shown potential utility in the prevention of chemotherapy-induced alopecia.
