A Series of Potent HIV-1 Protease Inhibitors Containing a Hydroxyethyl Secondary Amine Transition State Isostere: Synthesis, Enzyme Inhibition, and Antiviral Activity

A series of HIV-1 protease inhibitors containing a novel hydroxyethyl secondary amine transition state isostere has been synthesized.The compounds exhibit a strong preference for the (R) stereochemistry at the transition state hydroxyl group.Molecular modeling studies with the prototype compound 11 have provided important insights into the structural requirements for good inhibitor-active site binding interaction.N-Terminal extension of 11 into the P2-P3 region led to the discovery of 19, the most potent enzyme inhibitor in the series (IC50 = 5.4 nM). 19 was shown to have potent antiviral activity in cultured MT-4 human T-lymphoid cells.Comparison of analogs of 19 with analogs of 1 (Ro31-8959) demonstrates that considerably different structure-activity relationships exist between these two subclasses of hydroxyethylamine HIV-protease inhibitors.

Convenient method for the preparation of carbamates, carbonates, and thiocarbonates

(Chemical Equation Presented) A convenient, rapid, and efficient method for the preparation of carbamates from amines with 1-alkoxycarbonyl-3-nitro-1,2,4- triazole transfer reagents is reported. Reactions of newly synthesized stable crystalline reagents with alkyl amines were completed in a few minutes without any additional base, and highly pure carbamates were obtained without chromatographic purification. These highly active reagents are also useful for the selective protection of nucleobases and preparation of carbonates and thiocarbonates.

Prediction of maximum yield in the crystallization of multicomponent isomeric systems

We have developed a computer program (CRYSS), which may be used to rank the performance of a series of crystallization experiments. The method, at its simplest, allows the chemist to take composition data from partially purified crystallized solids and mother liquors; when this is coupled with initial composition data, the program can predict the maximum yield the system is capable of delivering after optimization. In this paper the underlying theoretical basis of the method is investigated by means of the crystallization of a three-component blend of hydrobenzoin isomers, along with the investigation of a four-component system based on aminoindanol. In the latter case, the modulation of purification performance via salt formation is demonstrated.

Stereoselective synthesis of P-stereogenic aminophosphines: Ring opening of bulky oxazaphospholidines

A highly diastereoselective and efficient synthesis of P-stereogenic bulky alkyl and aryl aminophosphines that relies on ring opening of tert-butyl-oxazaphospholidine 2 is described. Ring opening with several organometallic reagents takes place with inversion of configuration at the phosphorus center as it has been demonstrated by X-ray analysis of two ring-opened intermediates. The unprecedented reactivity observed is attributed to the presence of a free NH functionality that facilitates the attack of the organometallic reagent in an SN2@P-type process.

Process for the separation of a mixture of enantiomers

A diastereomer complex obtained via a process for the separation of enantiomers is disclosed, wherein separation can be rapidly effected such that enantiomers are obtained with high e.e. values. The process pets the separation of mixtures of enantiomers in which more than one resolving agent is used, of which at least one resolving agent is optically active, and which yields a diastereomer complex containing at least two resolving agents in optically active form. The process provides for, inter alia, a diastereomer complex having at least three compounds of which at least two compounds are resolving agents in optically active form, and at least one compound is an onantiomer in optically active form. Also provided is a diastereomer complex having at least three compounds of which at lea one compound is a resolving agent in optically active form, and at least two compounds which are enantiomers in optically active form.

Development of a novel fluorine-18 labeled deuterated fluororasagiline ([18F]fluororasagiline-D2) radioligand for PET studies of monoamino oxidase B (MAO-B)

The objective of this study was to synthesize and evaluate a novel fluorine-18 labeled deuterium substituted analogue of rasagiline (9, [ 18F]fluororasagiline-D2) as a potential PET radioligand for studies of monoamine oxidase B (MAO-B). The precursor compound (6) and reference standard (7) were synthesized in multi-step syntheses. Radiolabeling of 9 was accomplished by a two-step synthesis, compromising a nucleophilic substitution followed by hydrolysis of the sulfamidate group. The incorporation radiochemical yield from fluorine-18 fluoride was higher than 30%, the radiochemical purity was >99% and the specific radioactivity was >160 GBq/mumol at the time of administration. In vitro compound 7 inhibited the MAO-B activity with an IC50 of 173.0 ¡À 13.6 nM. The MAO-A activity was inhibited with an IC50 of 9.9 ¡À 1.1 muM. The fluorine-18 version 9 was characterized in the cynomolgus monkey brain where a high brain uptake was found (275% SUV at 4 min). There was a higher uptake in the striatum and thalamus compared to the cortex and cerebellum. A pronounced blocking effect (50% decrease) was observed in the specific brain regions after administration of l-deprenyl (0.5 mg/kg) 30 min prior to the administration of 9. Radiometabolite studies demonstrated 40% of unchanged radioligand at 90 min post injection. An efficient radiolabeling of 9 was successfully established and in the monkey brain 9 binds to MAO-B rich regions and its binding is blocked by the selective MAO-B compound l-deprenyl. The radioligand 9 is a potential candidate for human PET studies.

Exploring SAR features in diverse library of 4-cyanomethyl-pyrazole-3-carboxamides suitable for further elaborations as CB1 antagonists

A chemically diverse library of secondary and tertiary 4-cyanomethyl-1,5-diphenyl-1H-pyrazole-3-carboxamides was synthesized to enable mapping of the SAR, in the eastern amide region, with regard to CB1 antagonist activity, This study was initiated as a prelude to the design and synthesis of possible CB1 antagonists that do not readily pass the blood-brain-barrier. In general a range of modifications were found to be tolerated in this part of the molecule, although polar and especially charged groups did to a degree reduce the CB1 antagonistic activity. Several compounds with single-digit or even sub-nanomolar potency, suitable for further elaboration of the nitrile moiety, were identified.
