  Phthalates are synthetic chemicals used in many products of both industrial and medical importance. Approximately three million metric tons of phthalates are produced worldwide annually and are used in various sectors. Di-2-ethylhexyl phthalate (DEHP) is one of the most commonly used plasticizers. Chemically, they are loosely attached to Polyvinyl Chloride (PVC) based materials and with passage of time, leach to the surrounding environment. Phthalates are released from various sources and humans are exposed via, ingestion or inhalation. Different types of phthalates are used in the manufacture of coated and sustained releases drug formulations, as approved by FDA. Phthalates have been enlisted as Endocrine Disrupting Chemicals (EDCs) with proven toxicity on various hormone controlled functions. Currently, besides medical devices, over the counter and prescription drugs contain certain quantity of phthalate as excipient. In certain chronic diseases, treating patient with such drugs may be an additional direct exposure to phthalates toxicity. So, on the basis of gathered evidences there is a need to seriously consider this type of direct human exposure and prevent already suffering people from being chronically poisoned with phthalates.

  Drug discovery in different time frames provides a reflection in the struggle of scientists to generate synthetic products from a natural source. The complex processes exist in the development of the new drug from novel ideas. The duration may vary 10-15 year with estimation cost of $1.5 billion. The stratification of different assays involved in development phase leads to the acceptability of drug molecule. In the discovery phase, implementation of powerful techniques such as combinatorial chemistry and molecular modeling has also participated in the identification of drug target molecules. The advancement in molecular biology especially genomic science has also imparted a profound role in the discovery phase. However, with bioinformatics branch, it allows us to derive more suitable points for attacking the drug molecule in different disease conditions. However, the review will describe the preclinical stages, identification and validation of target through HTS (high throughput screening assay) and finally approval of drug molecule for further clinical development.

  From decades’ tuberculosis (TB) affecting individual and a huge number of people die every year. It causes ill-health among millions of individuals each year and ranks as the second leading cause of death from an infectious disease worldwide. The number of TB deaths has been unacceptably increased to a large extent and most cases are preventable if people get in time access to health care for a diagnosis and the right treatment. Multi-drug resistance is the fact that in TB patients are growing rapidly and difficult to treat. Treatment of MDR-TB is more complicated and longer than treatment of TB with no resistance. With advancements in the therapy of TB, now ideal treatments have been developed and many combination therapies are well recommended for MDR. The development of MDR-TB can be caused by a treatment that is inadequate, given the drug susceptibility pattern of the MTB strain. Few cohort studies provided information on treatment regimens and drug resistance profiles before treatment and at failure or recurrence or genotyping information at failure or recurrence. To monitor the development of acquired drug resistance, we suggest that given sufficient resources are available, TB treatment cohort studies or surveillance systems measure both the drug resistance profile and genotype information before starting treatment and at failure or recurrence. The emergence of MDR-TB and XDR-TB, the need for new TB drug regimens and rapid DST is intuiting globally. In future, more research with a focus on MDR and TB is required to avoid and counteract its associated complications.

  Malaria causes over a million deaths each year (2 percent of the global total of deaths), with hundreds of millions of clinical episodes per annum. The greatest challenge to malaria control and eradication is the emergence of malaria parasites that are resistant to antimalarial drugs. The development of resistance to conventionally used anti-malarial drugs, such as chloroquine (CQ) and Sulfadoxine-Pyrimethamine (SP) has been documented. To counter this WHO recommended that artemisinin-based combination therapy (ACT) should be used for treating uncomplicated Plasmodium falciparum malaria to ensure efficacy and reduce the emergence of drug-resistant parasites. Currently available antimalarial drugs are ineffective and their number is declining because of the widespread resistance. Thus, the new antimalarial agent is in urgent demand; however, the development of new antimalarial drug presents challenges due to resistance, toxicity, minimal efficacy of those on the pipeline and high cost of drug research. Identification of novel drug targets and design of new chemical compounds acting on new targets is important to control the emergence of resistance to existing drugs. In this regard, a natural product derived synthetic analogs of febrifugine containing quinazolinone scaffold can be considered best. Therefore, quinazolinones are potential compounds in seeking for novel drugs that act against the malarial pathogen. Hence, in this review compounds containing quinazolinone structure and possessing antimalarial activities are covered.
