Abstract
Development of novel derivatives to rein in and fight bacteria have never been more demanding, as microbial resistance strains are alarmingly increasing. A multitude of new fluoroquinolones derivatives with an improved spectrum of activity and/or enhanced pharmacokinetics parameters have been widely explored. Reporting novel antimicrobial agents entails comparing their potential activity to their parent drugs; hence, parent fluoroquinolones have been used in research as positive controls. Given that these fluoroquinolones possess variable activities according to their generation, it is necessary to include parent compounds and market available antibiotics of the same class when investigating antimicrobial activity. Herein, we provide a detailed guide on the in vitro biological activity of fluoroquinolones based on experimental results published in the last years. This work permits researchers to compare and analyze potential fluoroquinolones as positive control agents and to evaluate changes occurring in their activities. More importantly, the selection of fluoroquinolones as positive controls by medicinal chemists when investigating novel FQs analogs must be correlated to the laboratory pathogen inquest for reliable results.

Abstract
This paper reports on the design of a series of 10 novel lipophilic piperazinyl derivatives of the 1-cyclopropyl-6-fluoro-8-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid, their synthesis, their characterisation by 1H, 13C and 19F NMR, IR spectroscopy and HRMS, as well as their biological activity against bacteria of medical interest. Among these derivatives, 2 were as potent as the parent quinolone against Neisseriagonorrhoeae whereas all the compounds displayed lower activity than the parent quinolone against other bacteria of medical interest. Our results showing that the increased lipophilicity was deleterious for antibacterial activity may help to design new quinolone derivatives in the future, especially lipophilic quinolones which have been poorly investigated previously.

Abstract
Among all nitrogen-containing heterocycles, the 1,8-naphthyridine scaffold has recently gained an immense amount of curiosity from numerous researchers across fields of medicinal chemistry and drug discovery. This new attention can be ascribed to its versatility of synthesis, its reactiveness and the variety of biological activities it has exhibited. Over the past half-decade, numerous diverse biological evaluations have been conducted on 1,8-naphthyridine and its derivatives in a quest to unravel novel pharmacological facets to this scaffold. Its potency to treat neurodegenerative and immunomodulatory disorders, along with its anti-HIV, antidepressant and antioxidant properties, has enticed researchers to look beyond its broad-spectrum activities, providing further scope for exploration. This review is a consolidated update of previous works on 1,8-naphthyridines and their analogs, focusing on the past 5 years.

Abstract
The global spread of drug resistance in bacteria requires new potent and safe antimicrobial agents. Compounds containing the 1,2,4-triazole ring in their structure are characterised by multidirectional biological activity. A large volume of research on triazole and their derivatives has been carried out, proving significant antibacterial activity of this heterocyclic core. This review is useful for further investigations on this scaffold to harness its optimum antibacterial potential. Moreover, rational design and development of the novel antibacterial agents incorporating 1,2,4-triazole can help in dealing with the escalating problems of microbial resistance.

Abstract
Cancers are a high risk for humanity. In 2018, approximately 18 million new cancer cases
were diagnosed in the world. The choice of treatment depends on the type of cancer
and its stage at diagnosis. The treatment of cancer consists mainly of surgical methods,
radiotherapy, immunotherapy, hormone therapy and chemotherapy. Cytotoxic drugs can
be used both in monotherapy and combination therapy. In 2009-2018, the US. Food and
Drug Administration (FDA) approved about 356 new drugs for cancer therapy. However,
it should be noted that despite the increasing availability of modern drugs, this disease is
the second leading cause of death in the world. Research on the development of a cytotoxic
drug is aimed at designing a compound structure, whose action is directed at cancer
cells while not affecting normal cells. Triazine derivatives might be the chemical structure
with potential anticancer activity. This scaffold has been used in oncological therapy
since 1965. Depending on the location of the nitrogen atoms in the ring, three isomers
can be distinguished: [1,2,3]triazines, [1,2,4]triazines, [1,3,5]triazines. Modification of the
structure of the [1,2,4]triazine derivatives should provide stronger cytotoxic properties
and reduce the side effects of the novel drug. Designing new preparations also aims to
improve the patient’s quality of life. This review will briefly present how the modification of the chemical structure of [1,2,4]triazine derivatives increases their cytotoxic activity
against cancer and why these compounds may be better tolerated than current therapy.

Abstract
Antibiotics are commonly used to fight against bacterial infections, but bacteria have already been resistant to almost all antibiotics due to abuse of antibiotics. 1,2,4-Triazole derived compounds possess chemotherapeutic effects including potential antibacterial activities against drug-sensitive as well as drug-resistant pathogens. Hybridization displays a high potential to develop novel drugs with the capacity to overcome drug resistance, reduce toxicity and improve pharmacokinetic profiles. More effective antibacterial candidates might be obtained by the hybridization of 1,2,4-triazole with other antibacterial pharmacophores. This review summarizes the recent advances of 1,2,4-triazole derivatives as potential antibacterial compounds, and the structure-activity relationship is also discussed.

Abstract
In the present investigation, we carried a phytochemical study of an ethanol-soluble extract from the root barks of Aspidistra typica Baill., a traditional food and herb medicine, leading to the isolation of four different kinds of compounds, including one benzene substituted coumarin, two organic phosphonic compounds, and one xanthone. The novel benzene substituted coumarin typicacoumarin A (1) was a new type of coumarin, and the two new organic phosphonic compounds, typicalphosphine A (2) and typicalphosphine B (3) were isolated for the first time, and their structures were elucidated by spectral techniques, viz.1D, 2D NMR spectra and HR-ESI-MS. The xanthone compound typicaxanthone A (4) was discovered from nature for the first time. The two new organic phosphonic chlorides (2, 3) showed stronger antibacterial activities, which were comparable to berberine hydrochloride. And typicaxanthone A (4) showed much stronger antibacterial activity against Escherichia coli ATCC-25922 bacterial strain, while typicacoumarin A (1) showed moderate antibacterial activities, weaker than berberine hydrochloride.
