Abstract
Red-to-near-infrared (NIR) fluorescent probes, with advantages such as high spatiotemporal resolution and in situ sensing abilities, are highly attractive for diagnosis of gastrointestinal diseases and targeted drug development. However, conventional red-to-NIR fluorophores with electron closed-shell structures require tedious synthetic procedures for preparation, and it is difficult to further decorate them with sensing groups. In this study, a series of easily prepared pyrroles with simple structures that can quickly be transformed into red-to-NIR emissive radical cations in acidic buffer solution and in vivo stomachs is developed. The in-situ-generated red-to-NIR emissive pyrrole radical cations in the stomach have excellent biocompatibility and stability and can be used not only for intravital gastrointestinal imaging with high spatiotemporal resolution, but also for dynamic monitoring of the gastric emptying process and assessment of anti-gastric-acid therapy. The acidity-induced generation of pyrrole radical cations is believed to provide a facile strategy for developing red-to-NIR fluorophores and studying gastrointestinal diseases.

Abstract
We describe here for the first time the consistent observation of two metabotypes associated with resveratrol metabolism by the human gut microbiota, that is, lunularin (LUNU)-producers and LUNU non-producers. In healthy volunteers (n = 195), resveratrol was reduced to dihydroresveratrol, which only in the LUNU-producer metabotype was sequentially dehydroxylated at the 5-position to yield LUNU and the 3-position to produce 4-hydroxydibenzyl. These metabolites (also 3,4'-dihydroxy-trans-stilbene in some LUNU-producers) were detected in the urine and (or) feces of 74% of volunteers after consuming resveratrol, while 26% lacked these dehydroxylase activities. The LUNU non-producer metabotype was more prevalent in females (P < 0.05) but independent of individuals' BMI and age. A 4-styrylphenol reductase in both metabotypes converted stilbenes to their corresponding dibenzyls, while no 4-dehydroxylation in stilbenes or dibenzyls was observed. 4-Hydroxy-trans-stilbene, pinosylvin, dihydropinosylvin, 3-hydroxydibenzyl, and 3-hydroxy-trans-stilbene were not detected in vivo or in vitro. Further research on LUNU metabotypes, their associated gut microbiota, and their impact on health is worthwhile.

Abstract
Resveratrol (RSV) was known to be metabolised by the gut microbiota to dihydroresveratrol, lunularin (LUNU), and (or) 3,4'-dihydroxy-trans-stilbene (DHST). We describe here for the first time that LUNU can be further dehydroxylated, but only at the 3-position, to yield 4-hydroxydibenzyl, a novel metabolite found in human urine after RSV intake in 41 out of 59 healthy participants. In contrast, DHST was not further dehydroxylated, and thus, 4-hydroxy-trans-stilbene was not detected as a gut microbial metabolite of RSV. Faecal in vitro incubations confirmed the in vivo results.

Abstract
Herein, relationships between the structures of 1-aminoethyl-substituted chromenes and their antimalarial activities were thoroughly investigated. At first, the methyl moiety in the side chain was removed to eliminate chirality. The hydrogenation state of the benzopyran system, the position of the phenolic OH moiety, and the distance of the basic amino moiety toward both aromatic rings were varied systematically. 1-Benzopyran-5-ol 8b (IC50 = 10 nM), 1-benzopyran-7-ol 9c (IC50 = 38 nM), and the aminoalcohol 19c (IC50 = 17 nM) displayed antiplasmodial activity with IC50 values below 50 nM. To identify the mechanism of action, inhibition of three key enzymes by 9c was investigated. 9c was not able to reduce the number of Plasmodia in erythrocytes of mice. This low in vivo activity was explained by fast clearance from blood plasma combined with rapid biotransformation of 9c. Three main metabolites of 9c were identified by liquid chromatography-mass spectrometry (LC-MS) methods.

Abstract
Background:
Phenolic Mannich bases have been reported as acetylcholinesterase
(AChE) inhibitors for the medication of Alzheimer's disease. Carbonic Anhydrases (CAs) are molecular
targets for anticonvulsant, diuretic and antiglaucoma drugs in the clinic. Phenolic compounds
have also been mentioned as CA inhibitors. The importance of Mannich bases in drug design inspired
our research group to design novel phenolic Mannic bases as potent enzyme inhibitors.
Objective:
In this study, novel Mannich bases, 1-(3,5-bis-aminomethyl-4-hydroxyphenyl)-3-(4-
substitutedphenyl)-2-propen-1-ones (1-9), were designed to discover new and potent AChE inhibitors
for the treatment of Alzheimer's disease and also to report their carbonic anhydrase inhibitory
potency against the most studied hCA I and hCA II isoenzymes with the hope to find out promising
enzyme inhibitors.
Methods:
Mannich bases were synthesized by the Mannich reaction. The structures of the compounds
were elucidated by 1H NMR, 13C NMR, and HRMS. Enzyme inhibitory potency of the compounds
was evaluated spectrophotometrically towards AChE, hCA I and hCA II enzymes.
Results and Discussion:
The compounds showed inhibition potency in nanomolar concentrations
against AChE with Ki values ranging from 20.44±3.17 nM to 43.25±6.28 nM. They also showed
CAs inhibition potency with Ki values in the range of 11.76±1.29-31.09±2.7 nM (hCA I) and 6.08 ±
1.18-23.12±4.26 nM (hCA II). Compounds 1 (hCA I), 5 (hCA II), and 4 (AChE) showed significant
inhibitory potency against the enzymes targeted.
Conclusion:
Enzyme assays showed that Mannich derivatives might be considered as lead enzyme
inhibitors to design more selective and potent compounds targeting enzyme-based diseases.

Abstract
A series of eight polymethoxychalcone Mannich base derivatives 2a-2h was synthesized via
the microwave-assisted Mannich reaction of natural product 2'-hydroxy-3,4,4',5,6'-pentamethoxychalcone
(1) with various secondary amines and formaldehyde. Compared to conventional heating method
(80°C), the microwave-assisted method (700W, 65°C) is efficient with short reaction time (0.5-1 h) and
good yields (74-88%). The antiproliferative activities of eight Mannich base derivatives were evaluated
in vitro on a panel of three human cancer cell lines (Hela, HCC1954 and SK-OV-3) by CCK-8 assay.
The results showed that all of the Mannich base derivatives exhibited potential antiproliferative activities
on tested cancer cell lines with the IC50 values of 9.13-48.51 µM. Some active compounds exhibited
more activity as compared to positive control cis-Platin. Among them, compound 2b revealed to
have the strongest antiproliferative activity against all the three cancer cell lines with IC50 values ranging
from 9.13 to 11.24 µM.

Abstract
The effect on the bioactivity of antibacterial sulfonamide drugs against malaria and tuberculosis via an increase of the lipid solubility groups by condensation with a reduced chalcone was investigated. Sulfonamide derivatives (8a-8d) were obtained via a 1,3-diarylpropane scaffold, prepared by reduction of the relevant chalcones, followed by the addition of a sulfonamide moiety via the Mannich and the Mannich exchange reactions. The ClogP values indicated that the lipophilicities of 8a-8d and intermediate reduced chalcones and N-alkylated reduced chalcones (5a-7a) were much higher than those of the sulfonamides (1a-1c). The N-alkylated reduced chalcone derivatives 6 and 7 exhibited the highest antimalarial (Plasmodium falciparum (NF54 strain)) activity. Addition of the sulfonamide group weakened the activity, even though some ClogP values were higher, while 1a-1c showed no activity. The reduced chalcones 5a and 5 showed potent growth inhibition of Mycobacterium tuberculosis (H37Rv strain), but the sulfonamide derivatives 8a and 8d showed no or insignificant activity (0 and 14%, respectively) against M. tuberculosis, despite high ClogP values. Thus, the possible increase in bioactivity expected from an increase in ClogP values (lipophilicity) might be counteracted by the higher molecular weight of the studied analogues.

Abstract
A series of aurone Mannich base derivatives were designed, synthesized and evaluated as multifunctional agents for the treatment of Alzheimer's disease. In vitro assays demonstrated that most of the derivatives were selective AChE inhibitors with good multifunctional properties. Among them, compound 7d exhibited outstanding inhibitory activity for RatAChE, EeAChE and HuAChE (IC50 = 0.00878 ± 0.0002 μM, 0.0212 ± 0.006 μM and 0.0371 ± 0.004 μM, respectively). Moreover, 7d displayed high antioxidant activity and could confer significant neuroprotective effect against H2O2-induced PC-12 cell injury. In addition, 7d also showed biometal chelating abilities, good self- and Cu2+-induced Aβ1-42 aggregation inhibitory potency and high BBB permeability. These multifunctional properties highlight 7d as promising candidate for further studies directed to the development of novel drugs against AD.

Abstract
Malaria remains a great burden on humanity. Although significant advances have been made in the prevention and treatment of malaria, malaria control is now hindered by an increasing tolerance of the parasite to one or more drugs within artemisinin combination therapies; therefore, an urgent need exists for development of novel and improved therapies. The University of the Free State Chemistry Department previously synthesized an antimalarial compound, NP046. In vitro studies illustrated an enhanced efficacy against Plasmodium falciparum However, NP046 showed low bioavailability. Efforts to enhance the bioavailability of NP046 have resulted in the synthesis of a number of aminoalkylated diarylpropanes, including NP085 and NP102. Pharmacokinetic studies were conducted in C57BL/6 mice, with 15 mg/kg NP085 or NP102 administered orally and the 5 mg/kg NP085 or NP102 administered intravenously. Blood samples were collected by means of tail bleeding at predetermined time intervals. Drug concentrations were determined using a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, and subsequently pharmacokinetic modeling was done for both compounds. NP085 and NP102 were incubated in vitro with human and mouse liver microsomes. Both compounds were also subjected to a parallel artificial membrane permeation assay. In vitro studies of NP085 and NP102 illustrated that both of the compounds are rapidly absorbed and undergo rapid hepatic metabolism. The maximum concentration of drug (Cmax) obtained following oral administration of NP085 and NP102 was 0.2 ± 0.4 and 0.7 ± 0.3 μM, respectively; the elimination half-life of both compounds was 6.1 h. NP085 and NP102 showed bioavailability levels of 8% and 22%, respectively.
