Abstract
Cyclic N-sulfonyl aldimines are well-known aza-[2C]-synthons for various [2 + n] annulation reactions. Herein we describe a novel base mediated [2 + 1] annulation and a regioselective aziridine ring-opening reaction cascade, which provides an efficient and distinct synthetic strategy from readily available cyclic N-sulfonyl aldimines and α-carbonyl sulfonium salts leading to β-amino ketone derivatives through the corresponding fused tri-substituted aziridines. This one-pot, two-step process involves formation of C-C and C-N bonds and subsequent cleavage of a C-N bond. The features of the developed reaction include the use of mild reaction conditions, broad substrate scope, and excellent yields. The synthetic utility of this approach was demonstrated by gram-scale operation and further product derivatizations.

[PMID: 36271321 DOI: 10.1111/cbdd.14157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 09/27/2022] [Accepted: 10/16/2022] [Indexed: 11/28/2022]
Abstract
This article describes studies on the design, synthesis, and biological evaluation of pyrazole-containing β-amino carbonyl compounds (5a-5q) as DPP-4 inhibitors and anti-diabetic agents. In contrast, mannich reactions went smoothly with bismuth nitrate (Bi (NO3 )3 ) catalyst in the presence of ethanol and produced pyrazole-containing β-amino carbonyl compounds in good yield. Molecular docking studies of designed derivatives with DPP-4 enzyme (PDB: 2OLE), compounds 5d, 5h, 5j, and 5k showed excellent interaction. 3D QSAR and pharmacophoric model studies were also carried out. ADMET parameters, pharmacokinetic properties, and in vivo toxicity studies further confirmed that all the designed compounds were found to have good bioavailability and were less toxic. Further, these compounds were evaluated as enzyme-based in vitro DPP-4 inhibitory activity, and 5d, 5h, 5i, 5j, and 5k exhibited IC50 toward DPP-4 enzyme of 10.52, 10.41, 5.55, 4.16, and 7.5 nM, respectively. The most potent compound, 5j, was further selected for in vivo anti-diabetic activity using an STZ-induced diabetic mice model, and 5j showed a significant diabetic control effect.

Abstract
Multicomponent reactions (MCRs) are composed of three or more reagents in which the final
product has all or most of the carbon atoms from its starting materials. These reactions represent, in the
medicinal chemistry context, great potential in the research for new bioactive compounds, since their products
can present great structural complexity. The aim of this review is to present the main multicomponent reactions
since the original report by Strecker in 1850 from nowadays, covering their evolution, highlighting their
significance in the discovery of new bioactive compounds. The use of MCRs is, indeed, a growing field of
interest in the synthesis of bioactive compounds and approved drugs, with several examples of commerciallyavailable
drugs that are (or can be) obtained through these protocols.

Abstract
Background:
Diabetes mellitus is the third-largest non-communicable chronic disease
worldwide. There are many effective drugs, but the long-term use of these clinical drugs may cause
various side effects. Therefore, it is urgent to develop new antidiabetic molecules with higher efficacy
and lower toxicity.
Methods:
Fifteen new 3-aryl-1-(5-methylisoxazol-3-ylamino)-1-(4-nitrophenyl)propan-1-one were
synthesized directly through the Mannich reaction of 4-nitroacetophenone, 3-amino-5-
methylisoxazole and aromatic aldehydes catalyzed by concentrated hydrochloric acid. The molecular
structures of the products were fully characterized by 1H NMR, 13C NMR, ESI MS and HRMS.
The peroxisome proliferator-activated receptor (PPAR) response element and α-glucosidase inhibitory
activity of these compounds were evaluated in vitro. Molecular docking, molecular physical
parameters calculation, and molecular toxicity prediction were performed to analyze the structure-
activity relationship and evaluate the druggability of these compounds theoretically.
Results:
All compounds exhibited weak antidiabetic activities, but compound 15 showed promising
as a high performance, dual-target antidiabetic lead compound with peroxisome proliferatoractivated
receptor (PPAR) response element relative agonist activity of 99.55% at 27.2 nmol·mL−1
and α-glucosidase inhibitory activity of 35.21% at 13.6 nmol·mL−1. All compounds obtained may
have no cardiotoxicity, no acute toxicity, no carcinogenic, and within safe range of mutagenic risk.
Conclusion:
This study identified a potential PPAR lead molecule and presented an unusual strategy
for antidiabetic drug development.

Abstract
The biological activity of Mannich bases, a structurally heterogeneous class of chemical compounds that are generated from various substrates through the introduction of an aminomethyl function by means of the Mannich reaction, is surveyed, with emphasis on the relationship between structure and biological activity. The review covers extensively the literature reports that have disclosed Mannich bases as anticancer and cytotoxic agents, or compounds with potential antibacterial and antifungal activity in the last decade. The most relevant studies on the activity of Mannich bases as antimycobacterial agents, antimalarials, or antiviral candidates have been included as well. The review contains also a thorough coverage of anticonvulsant, anti-inflammatory, analgesic and antioxidant activities of Mannich bases. In addition, several minor biological activities of Mannich bases, such as their ability to regulate blood pressure or inhibit platelet aggregation, their antiparasitic and anti-ulcer effects, as well as their use as agents for the treatment of mental disorders have been presented. The review gives in the end a brief overview of the potential of Mannich bases as inhibitors of various enzymes or ligands for several receptors.
