RESUMEN
Cancer formation is defined as the unrestrained proliferation of cells due to various factors acting as a causing agent. A limited number of over-expressed transcription factors are contributed to the development of numerous types of cancer. The metastatic regulator protein BTB And CNC Homology 1 (BACH1) is Cap 'N' Collar (CNC) and it belongs to a basic region leucine zipper (bZIP) family. The presence of the least level concentration of intracellular heme BACH1 forms heterodimers with musculo aponeurotic fibrosarcoma (sMAF) proteins and inhibits or induces the target gene expression. Based on the previous studies, BACH1 plays a critical player in the conditions of senescence and oxidative stress, cycling of cell life, heme degradation pathway and cancer, especially in metastasis. Discovering new anti-cancer drugs (identification of bioactive compounds) stages finally needs to inhibit the target protein. This present study is aimed to screen and identify stability, binding affinity and analysis of pharmacokinetics of selected compounds through structural screening, ADMET, DFT and MESP. From this study, it is revealed that Rapanone and Nectandrin B have the potential to alter the degree of gene expression via binding with the BACH1 allosteric region which will further change the degree of expression of BACH1 downstream target genes involved in the regulation of cancer progression particularly in metastasis. The two plant origin compounds Rapanone and Nectandrin B might be novel candidates for developing anti-cancer drugs. The predicted compounds were further validated through in-vitro experimental approaches.Communicated by Ramaswamy H. Sarma.
RESUMEN
This review is intended to provide an updated summary of, but not limited to, classification, etiopathogenesis, diagnosis, and treatment strategies for insomnia disorder. The severity of insomnia symptoms irrespective of co-existing primary medical condition/s in the studied patients classified insomnia as 'insomnia disorder' to prioritize the clinical attention on insomnia (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition). The frequency and duration of symptoms further divided insomnia into chronic, short-term, and other insomnia disorder (International Classification of Sleep Disorders, Third Edition). This disorder is a phenomenal state of hyperarousal developed and perpetuated by environmental, behavioral, cognitive, genetic, socioeconomic, preexisting medical factors. Overarching physiological, cortical, behavioral, and cognition changes in hyperarousal manifest insomnia disorder. It, sometimes, leads to the co-occurrence of other chronic medical condition/s. The contemporary diagnosis of insomnia disorder needs to consider modified diagnostic criteria, growing evidence on insomnia disorder symptoms, associated factors, co-existing medical condition/s (if any) to identify the subjective severity of insomnia disorder and design a treatment plan. The recommended treatment strategies include cognitive-behavioral therapy for insomnia (CBTI) and pharmacotherapy. However, CBTI lacks accessibility, qualified facilitators, and pharmacotherapy has limitations like side effects, physiological tolerance/dependence. The investigation of phytocompounds subdued these drawbacks of existing treatments as some compounds showed anti-insomniac potential. Furthermore, complementary alternative medicines (CAMs) like mindfulness-based practices, acupuncture, listening to music, Yogasanas, Pranayama, digital cognitive behavioral therapy for insomnia (dCBTI) during bedtime proved supportive in insomnia disorder treatment.

A limited number of overexpressed transcription factors are associated with cancer progression in many types of cancer. BTB and CNC homology 1 (BACH1) is the first mammalian heme-binding transcription factor that belongs to the basic region leucine zipper (bZIP) family and a member of CNC (cap 'n' collar). It forms heterodimers with the small musculoaponeurotic fibrosarcoma (MAF) proteins and stimulates or suppresses the expression of target genes under a very low intracellular heme concentration. It possesses a significant regulatory role in heme homeostasis, oxidative stress, cell cycle, apoptosis, angiogenesis, and cancer metastasis progression. This review discusses the current knowledge about how BACH1 regulates cancer metastasis in various types of cancer and other carcinogenic associated factors such as oxidative stress, cell cycle regulation, apoptosis, and angiogenesis. Overall, from the reported studies and outcomes, it could be realized that BACH1 is a potential pharmacological target for discovering new therapeutic anticancer drugs.
