Despite recent advances, cancer remains the leading cause of death on a global scale. Various types of research have been conducted in order to discover novel and effective anticancer medications. The complexity of breast cancer, combined with patient-to-patient variations and heterogeneity between cells within the tumour, is a major challenge. That problem is expected to be solved by revolutionary drug delivery. Chitosan nanoparticles have the potential to be a game-changing delivery system capable of increasing anticancer drug activity while decreasing negative effects on normal cells. The use of smart drug delivery systems as delivering materials to improve the bioactivity of NPs and to better understand the complexities of breast cancer has piqued the interest of many researchers. Current therapies are still ineffective in eradicating the disease as a whole, necessitating advancement through the use of far more specific treatments. Conventional chemotherapy employs poorly water-soluble drugs with limited delivery to target tissues, which leads to the development of resistant tumours, high drug toxicity in normal cells, severe side effects, rapid degradation, low specificity, and limited targeting. The main challenges in cancer therapy are drug development and drug delivery systems.

Cancer is a complex disease, and treating it is difficult due to the variable efficacy of conventional anticancer drugs. A two-drug cocktail hybrid approach is a recent drug discovery strategy that involves combining two drug pharmacophores into a single molecule. The hybrid molecule acts on multiple targets simultaneously through distinct modes of action, resulting in greater efficacy and less susceptibility to resistance. As a result, there is enormous potential for using hybrid compounds to address the current challenges in cancer medicine. Recent research has used this technique to discover some intriguing molecules with significant anticancer properties. We present data on a number of promising hybrid anti-proliferative/ anti-tumor agents developed over the previous ten years in this study. Quinazoline, indole, carbazole, pyrimidine, quinoline, quinone, imidazole, selenium, platinum, hydroxamic acid, ferrocene, curcumin, triazole, benzimidazole, isatin, pyrrolo benzodiazepine (PBD), chalcone, coumarin, nitrogen mustard, pyrazole, and pyridine-based anticancer hybrids are examples. Overall, this review demonstrates the potential benefits of combining pharmacophoric subunits from various known chemical prototypes to create more potent and precise hybrid compounds. This is useful information for researchers working on complex diseases like cancer.

The evaluation of thiazole's biological activity, such as antibacterial, antiprotozoal, antitubercular, antifungal and anthelmintic, with an emphasis on their potential medicinal applications, is desirable because the thiazole has an important component effect on the pharmacophores of a large number of medicinally significant molecules. We are particularly interested in investigating newly synthesized aminothiazoles, particularly 2-aminothiazole derivatives, a class of heterocyclic ring systems with antiviral, antimicrobial, anticancer and anti-inflammatory properties, respectively. Numerous human cancer cell lines, including breast, leukemia, lung, colon, CNS, melanoma, ovarian, renal and prostate cell lines, were the subjects of previous in vitro anticancer evaluation studies of a variety of 2-aminothiazole analogs. In its use as a core structure in a variety of therapeutic applications, substitutions at the 2-position of benzothiazole have emerged. Interesting results from studies on the structure-activity relationship show that changing the structure of a substituent group at its C-2 position frequently alters its bioactivity. Although 2-substituted benzothiazoles have numerous therapeutic applications, their anti-inflammatory activity has not been extensively studied. Additionally, the numerous pharmaceutical applications of thiazole derivatives have sparked a lot of interest. A wide range of biological properties can be found in thiazole derivatives, including cardiotonic, fungicidal, sedative, anesthetic, bactericidal and anti-inflammatory properties. Thiazole derivatives are also said to have a wide range of biological activities.
