Azetidinones (Azetidin-2-ones), more commonly known as β-lactams, are well-known heterocyclic moieties among the medicinal compounds mainly because of their diverse pharmacological activities such as antimicrobial, anti-inflammatory, anticonvulsant, anti-HIV, anti-parkinsonian, antidiabetic and antitubercular activities. Various com-parative studies of current azetidinone derivatives show an alarming increase in the bacterial resistance to the β-lactam nucleus may be due to irrational usage, which unfortunately led to less therapeutic usage. Hence new hybrids of Azetidinones with other drugs containing different heterocyclic rings found to possess broad-spectrum efficacy against various types of bacteria with β-lactamase inhibition to find great scope for future needs. This concept of hybrid molecules of different heterocyclic drugs would be a cost-effective and time-saving experiment in the process of drug discovery and development. In today’s world of diseases and expensive drugs which are not affordable for countries like India, this attempt would be noon. Hence this review is an attempt to focus on the possible hybrid molecules of Azetidinones with other heterocyclic drugs for various...

In an attempt of synthesizing some novel and potent antioxidant activity having compounds, here some novel quinoline derivatives are reported. Initially using Vilsemeir-Hack reagent method 7-methyl or 8-methyl substituted 2-cholro-3-formylquinolines (Ia, b) were prepared. Further 7-methyl or 8-methyl substituted 2-hydroxy quinoline-3-carbaldehyde (IIa, b) were synthesized by the reaction of compound (I) on microwave irradiation with 4M HCl, which on further treatment with different substituted hydrazides yielded the novel Schiff bases of quinoline III (a-f). Purity of the synthesized compounds was determined by TLC and melting point. The structure of all newly synthesized compounds was confirmed by spectral studies such as IR, 1H NMR, 13C NMR, and mass spectroscopy. All the synthesized compounds were screened for in-vitro antioxidant activity by free radical scavenging activity by DPPH assays method and ferric ion reduction method using ascorbic acid as the standard drug. Screening results showed that all compounds are exhibiting moderate to good activity. Especially compounds III b, III d, and III f showed significant antioxidant...

Euphorbia hirta Linn. (Euphorbiaceae), commonly known as ‘Dudhy’ is an annual medicinal herb of Kumaun Himalaya Uttarakhand. It is an invasive plant used in conventional medicine to treat various diseases such as gastrointestinal disorders, respiratory system disorders, and asthma. The present review is designed to compile updated information on E. hirta, including its medicinal uses, phytochemicals, as well as biological activities. Qualitative and quantitative phytochemical studies on E. hirta revealed the presence of various chemical compounds in which flavonoids, terpenoids, and phenols are the major constituents. These monomeric compounds and crude extracts from E. hirta have also been screened for pharmacological activities in-vivo and in-vitro. Different parts of the plant have interesting antimicrobial, antioxidant, antidiabetic, and antitumor properties. Some traditional uses of this plant, such as in gastrointestinal disorders, bronchitis, and asthma, also indicated its high medicinal potentiality. E. hirta has been proved a valuable medicinal plant for the tribal people living in the rural region of Kumaun Himalaya. The crude hydroalcoholic extract of E. hirta has more pharmacological...

The Screening of medicinal plants for the new bioactive compounds leads to the development of new anti-microbial drugs that possess lesser cost and greater safety and efficacy. The increasing bacterial resistance exhibited by microorganisms causing skin infections has led to the research on medicinal plants. Argemone Mexicana Linn is a weed that shows multiple health benefits. All the parts of the plant are traditionally well known for the treatment of skin diseases. The aim of present study is to investigate and compare the anti-microbial activity of aqueous and ethanol extract of leaves of Argemone mexicana Linn against skin infection-causing bacteria. Also, Functional groups associated with phytochemical compounds of these plant extracts are well understood from FTIR Spectroscopy. The Argemone mexicana Linn leaves extract shows significant anti-microbial activity against all the selected microorganisms for study. The results for anti-microbial activity were recorded in zones of inhibitions. The highest zone of inhibition had shown by the ethanol extract at higher concentration, i.e., 300 mg/ml against all pathogens. The MIC values of...

Ticagrelor is a platelet aggregation inhibitor. It is used for the prevention of stroke, heart attack, and other events in people with the acute coronary syndrome, meaning problems with the blood supply in the coronary arteries. It acts as a platelet aggregation inhibitor by antagonising the P2Y 12 receptor. Its half-life is up to 12 h with the hepatic type of metabolism and biliary excretion. This review provides the pharmacokinetic and pharmacodynamics of the Ticagrelor, which also includes the review on pharmaceutical analytical techniques like High-performance liquid chromatography, Reverse phase – High-performance liquid chromatography, Bio-analytical techniques, UV spectrometry with the impurities, pharmaceutical dosage forms, bulk, and its formulations used for determination and validation. This review helps us to get updated information on validation of drug-Ticagrelor till current...
