Nucleophilic substitutions of benzylic alcohols with sulfamides were achieved using an FeCl3 Lewis acid catalyst in MeNO2. It was necessary to adjust the reaction conditions to obtain efficient yields depending on the stability of the carbocation intermediates. The reaction could easily be performed, and it was revealed that a variety of diarylmethanols and benzylic alcohols were applicable to the reaction, irrespective of the type and position of the substituents. The sulfamide moieties were easily deprotected and converted into amine groups.

Enantioselective reduction of ketimines was demonstrated using chiral N-heterocyclic carbene (NHC)-stabilised borenium ions in frustrated Lewis pair catalysis. High levels of enantioselectivity were achieved for substrates featuring secondary N-alkyl substituents. Comparative reactivity and mechanistic studies identify key determinants required to achieve useful enantioselectivity and represent a step forward in the further development of enantioselective FLP methodologies.

We report on catalysis by a fuel-induced transient state of a synthetic molecular machine. A [ 2] rotaxane molecular shuttle containing secondary ammonium/amine and thiourea stations is converted between catalytically inactive and active states by pulses of a chemical fuel (trichloroacetic acid), which is itself decomposed by the machine and/or the presence of additional base. The ON-state of the rotaxane catalyzes the reduction of a nitrostyrene by transfer hydrogenation. By varying the amount of fuel added, the lifetime of the rotaxane ON-state can be regulated and temporal control of catalysis achieved. The system can be pulsed with chemical fuel several times in succession, with each pulse activating catalysis for a time period determined by the amount of fuel added. Dissipative catalysis by synthetic molecular machines has implications for the future design of networks that feature communication and signaling between the components.

The isomerization of epoxides to aldehydes using the readily available Crabtree’s reagent is described. The aldehydes were transformed into synthetically useful amines by a one-pot reductive amination using pyrrolidine as imine-formation catalyst. The reactions worked with low catalyst loadings in very mild conditions. The procedure is operationally simple and tolerates a wide range of functional groups. A DFT study of its mechanism is presented showing that the isomerization takes place via an iridium hydride mechanism with a low energy barrier, in agreement with the mild reaction conditions.

We report on a switchable rotaxane molecular shuttle that features a pseudo-meso 2,5-disubstituted pyrrolidine catalytic unit on the axle whose local symmetry is broken according to the position of a threaded benzylic amide macrocycle. The macrocycle can be selectively switched (with light in one direction; with catalytic acid in the other) with high fidelity between binding sites located to either side of the pyrrolidine unit. The position of the macrocycle dictates the facial bias of the rotaxane-catalyzed conjugate addition of aldehydes to vinyl sulfones. The pseudo-meso non-interlocked thread does not afford significant selectivity as a catalyst (2-14 % ee), whereas the rotaxane affords selectivities of up to 40 % ee with switching of the position of the macrocycle changing the handedness of the product formed (up to 60 % Delta ee).

The capsid protein (CA) of HIV-1 plays essential roles in multiple steps of the viral replication cycle by assembling into functional capsid core, controlling the kinetics of uncoating and nuclear entry, and interacting with various host factors. Targeting CA represents an attractive yet underexplored antiviral approach. Of all known CA-targeting small molecule chemotypes, the peptidomimetic PF74 is particularly interesting because it binds to the same pocket used by a few important host factors, resulting in highly desirable antiviral phenotypes. However, further development of PF74 entails understanding its pharmacophore and mitigating its poor metabolic stability. We report herein the design, synthesis, and evaluation of a large number of PF74 analogs aiming to provide a comprehensive chemical profiling of PF74 and advance the understanding on its detailed binding mechanism and pharmacophore. The analogs, containing structural variations mainly in the aniline domain and/or the indole domain, were assayed for their effect on stability of CA hexamers, antiviral activity, and cytotoxicity. Selected analogs were also tested for metabolic stability in liver microsomes, alone or in the presence of a CYP3A inhibitor. Collectively, our studies identified important pharmacophore elements and revealed additional binding features of PF74, which could aid in future design of improved ligands to better probe the molecular basis of CA-host factor interactions, design strategies to disrupt them, and ultimately identify viable CA-targeting antiviral leads.

The bifunctional ligand p-SCN-Bn-HOPO, which has four 1,2-hydroxypyridinone groups on a spermine backbone with an isothiocyanate linker, has been shown to be an efficient and stable chelator for Zr(iv) and, more importantly, the radioisotope Zr-89 for use in radiolabeling antibodies for positron emission tomography (PET) imaging. Previous studies of Zr-89-HOPO-trastuzumab in mice showed low background, good tumor to organ contrast, and very low bone uptake which show p-SCN-Bn-HOPO to be an important next-generation bifunctional chelator for radioimmunoPET imaging with Zr-89. However, the reported synthesis of p-SCN-Bn-HOPO involves nine steps and multiple HPLC purifications with an overall yield of about 1.4%. Herein we report an improved and efficient synthesis of p-SCN-Bn-HOPO in four steps with 14.3% overall yield which will improve its availability for further biological studies and wider application in PET imaging. The new synthetic route also allows variation in linker length and chemistries which may be helpful in modifying in vivo clearance behaviors of future agents.

Recommanded Product: 91-00-9. I found the field of Pharmacology & Pharmacy; Chemistry very interesting. Saw the article Position of lipidation influences anticancer activity of Smac analogs published in 2019.0, Reprint Addresses Ruchala, P (corresponding author), Univ Calif Los Angeles, Dept Psychiat & Biobehav Sci, 760 Westwood Plaza, Los Angeles, CA 90024 USA.; Ruchala, P (corresponding author), Jane & Terry Semel Inst Neurosci & Human Behav, Pasarow Mass Spectrometry Lab, 760 Westwood Plaza, Los Angeles, CA 90024 USA.. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine.

A small group of lipid-conjugated Smac mimetics was synthesized to probe the influence of the position of lipidation on overall anti-cancer activity. Specifically, new compounds were modified with lipid(s) in position 3 and C-terminus. Previously described position 2 lipidated analog M11 was also synthesized. The resulting mini library of Smacs lipidated in positions 2, 3 and C-terminus was screened extensively in vitro against a total number of 50 diverse cancer cell lines revealing that both the position of lipidation as well as the type of lipid, influence their anti-cancer activity and cancer type specificity. Moreover, when used in combination therapy with inhibitor of menin-MLL1 protein interactions, position 2 modified analog SM2 showed strong synergistic anti-cancer properties. The most promising lipid-conjugated analogs SM2 and SM6, showed favorable pharmacokinetics and in vivo activity while administered subcutaneously in the preclinical mouse model. Collectively, our findings suggest that lipid modification of Smacs may be a viable approach in the development of anti-cancer therapeutic leads.
