The compounds of formula (I) and their pharmaceutically usable addition salts possess valuable pharmacological properties. Specifically, it has been found that the compounds of the present invention, alone or in combination with other therapeutic active compounds, have an activity as chemotherapeutic agents against cancer and, more particularly, pancreatic cancers.

Are antimalarial hybrid molecules a close reality or a distant dream?

Emergence of drug-resistant Plasmodium falciparum strains has led to a situation of haste in the scientific and pharmaceutical communities. Hence, all their efforts are redirected toward finding alternative chemotherapeutic agents that are capable of combating multidrug-resistant parasite strains. In light of this situation, scientists have come up with the concept of hybridization of two or more active pharmacophores into a single chemical entity, resulting in “antimalarial hybrids.” The approach has been applied widely for generation of lead compounds against deadly diseases such as cancer and AIDS, with a proven potential for use as novel drugs, but is comparatively new in the sphere of antimalarial drug discovery. A sudden surge has been evidenced in the number of studies on the design and synthesis of hybrids for treating malaria and may be regarded as proof of their potential advantages over artemisinin-based combination therapy (ACT). However, it is evident from recent studies that most of the potential advantages of antimalarial hybrids, such as lower toxicity, better pharmacokinetics, and easier formulation, have yet to be realized. A number of questions left unaddressed at present need to be answered before this approach can progress to the late stages of clinical development and prove their worth in the clinic. To the best of our knowledge, this compilation is the first attempt to shed light on the shortcomings that are surfacing as more and more studies on molecular hybridization of the active pharmacophores of known antimalarials are being published.

Synthesis of (¡À)-coerulescine and a formal synthesis of (¡À)-horsfiline

A straightforward synthesis of (¡À)-coerulescine and (¡À)-horsfiline has been established from 3-formyl-3-phenylpyrrolidine employing 4-hydroxypiperidine as the starting material. There are two remarkable steps for the synthesis of (¡À)-coerulescine and (¡À)-horsfiline. One is the rapid access to produce 3-formyl-3-phenylpyrrolidine by Lewis acid-catalyzed rearrangement of 3,4-dihydroxy-4-phenylpiperidine. The other key step is an intramolecular electrophilic cyclization from 3-benzylcarbamoyl-3- phenylpyrrolidine to the 3,3-spirocyclic 2-oxindole ring skeleton.

A reusable P, N-doped carbon quantum dot fluorescent sensor for cobalt ion

In this work, phosphorus, nitrogen co-doped carbon quantum dots (P,N-CQDs) as highly selective fluorescent probe for cobalt ion (Co2+) detection were designed and synthesized via a one-step hydrothermal protocol by employing pyridoxal 5-phosphate and ethanediamine. This probe enables selective detection of Co2+ with a linear range of 0?60 muM and a limit of detection of 0.053 muM through variation in fluorescence with respect to target concentration and electron-transfer from P,N-CQDs to Co2+. Furthermore, ethylenediaminetetraacetic acid-modified Fe3O4@SiO2 (Fe3O4@SiO2-EDTA) was tailor-designed and prepared to successfully realize the recovery of P,N-CQDs/Co2+ fluorescence for the first time. The reusable P,N-CQDs as fluorescent sensors for Co2+ also show good linearity and sensitivity. Ultimately, this fluorescent probe was applied in the analysis of real river water samples.
