Abstract
We have developed a simple and convenient method for the synthesis of substituted-aryllidine-2,2-dimethyl-7-thioxo/oxo-4H-[1,3]dioxino[4,5-d]pyrimidine derivatives (4a-g) via one-pot Biginelli reaction of Meldrum's acid (1), indole-3-carbaldehyde/thiophene-2-carbaldehyde/2-chloro-quinoline-3-carbaldehyde (2) and amines (3) in aqueous ethanol in the presence of a catalytic amount of CAN. The obtained pyrimidine hybrids were screened for their antimycobacterial activity against Mycobacterium tuberculi H37RV strain. The antimycobacterial results showed that compounds 4a and 4b exhibited excellent activity with MIC value of 1.6 µg/mL, four-fold greater than the standard streptomycin (6.24 µg/mL), while compounds (4c-g) showed lower efficacy. To study the interaction between the synthesized compounds and receptor, the compounds 4a, 4b, 4c, and 4d were studied for molecular docking on the enzyme enoyl-acyl carrier protein reductase (enoyl-ACP reductase) and the compounds 4a and 4b have emerged as active antitubercular agents with least binding energy -9.4 kcal/mol and -9.3 kcal/mol respectively.

Abstract
Nontuberculous mycobacteria (NTM) are the causative agent of severe chronic pulmonary diseases and is accountable for post-traumatic wound infections, lymphadenitis, endometritis, cutaneous, eye infections and disseminated diseases. These infections are extremely challenging to treat due to multidrug resistance, which encompasses the classical and existing antituberculosis agents. Hence, current studies are aimed to appraise the antimycobacterial activity of flavonoids against NTM, their capacity to synergize with pharmacological agents and their ability to block virulence. Flavonoids have potential antimycobacterial effects at minor quantities by themselves or in synergistic combinations. A cocktail of flavonoids used with existing antimycobacterial agents is a strategy to lessen side effects. The present review focuses on recent studies on naturally occurring flavonoids and their antimycobacterial effects, underlying mechanisms and synergistic effects in a cocktail with traditional agents.

Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB) remains one of the deadliest, infectious diseases worldwide. The detrimental effects caused by the existing anti-TB drugs to TB patients and the emergence of resistance strains of M. tuberculosis has driven efforts from natural products researchers around the globe in discovering novel anti-TB drugs that are more efficacious and with less side effects. There were eleven main review publications that focused on natural products with anti-TB potentials. However, none of them specifically emphasized antimycobacterial phenolic compounds. Thus, the current review’s main objective is to highlight and summarize phenolic compounds found active against mycobacteria from 2000 to 2017. Based on the past studies in the electronic databases, the present review also focuses on several test organisms used in TB researches and their different distinct properties, a few types of in vitro TB bioassay and comparison between their strengths and drawbacks, different methods of extraction, fractionation and isolation, ways of characterizing and identifying isolated compounds and the mechanism of actions of anti-TB phenolic compounds as reported in the literature.

Abstract
The present study proposes a discussion about the use of breakpoints when plant derivatives are used for investigating potential agents against Mycobacterium tuberculosis strains. A systematic review on these aspects was performed and supported that an arbitrary breakpoint may be considered inadequate in this kind of study. In addition, we propose that the adoption of this limiter should be done from the toxicity value found using the same plant derivative.

Abstract
Tuberculosis remains a major health problem accentuated by the rise of resistance to all available drugs. Therefore, this study was launched to discover a novel antituberculosis agent from wild Egyptian Sahara plants. Twelve such plants were screened, in vitro, for their activity against various Mycobacterium species. The most active plant, Euphorbia paralias, was further fractionated with different organic solvents, and the activity of the obtained fractions was determined by the agar diffusion and broth microdilution methods. The methanol fraction was the most active against Mycobacterium spp., and was non-toxic in doses up to 10 g/kg of animal weight. Its main component was separated by column chromatography, and then identified by ultraviolet spectroscopy and nuclear magnetic resonance analysis as quercetin-3-O-β-D-glucoside. Docking analysis suggested that quercetin-3-O-β-D-glucoside inhibits the glutamine synthetase enzyme, a promising target for the development of antituberculosis drugs. This prediction was confirmed by an in vitro glutamine synthetase biosynthetic assay. To the best of our knowledge, and based on bioinformatics mining of the BioPhytMol database, this is the first report on the antimycobacterial activity of Euphorbia paralias plant. It is also the first report on the inhibition of mycobacterial glutamine synthetase by the flavonoid quercetin.

Abstract
Due to the growing problem of drug resistant Mycobacterium tuberculosis strains, coupled with the twinning of tuberculosis (TB) to human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), the burden of TB is now difficult to manage. Therefore, new antimycobacterial agents are being sought from natural sources. This review focuses on natural antimycobacterial agents from endophytes and medicinal plants of Africa, Europe, Asia, South America and Canada. In the countries mentioned in this review, numerous plant species display putative anti-TB activity. Several antimycobacterial chemical compounds have also been isolated, including: ellagitannin punicalagin, allicin, anthraquinone glycosides, iridoids, phenylpropanoids, beta-sitosterol, galanthimine, crinine, friedelin, gallic acid, ellagic acids, anthocyanidin, taraxerol, termilignan B, arjunic acid, glucopyranosides, 1-epicatechol, leucopelargonidol, hydroxybenzoic acids, benzophenanthridine alkaloids, neolignans, and decarine. These compounds may provide leads to novel and more efficacious drugs to lessen the global burden of TB and drug-resistant M. tuberculosis strains. If there is a long-term remedy for TB, it must lie in nature's pharmacy of putative antimycobacterial agents.
