The Introduction of Small Molecule Inhibitors:
Small molecule inhibitors are a class of small molecules that interact with proteins and reduce the biological activity of target proteins. The structure of small molecule inhibitors has good spatial dispersion, and their chemical properties determine their good pharmacodinemic and pharmacokinetic properties. Small molecule inhibitors commonly used in drug research and development at present mainly include enzyme inhibitors and transcription factor inhibitors. The emergence of small molecule inhibitors has become one of the important pillars of cell biology research. Small molecule inhibitors provide an excellent opportunity to study many aspects of cell biology, from cell cycle control and mitosis to signaling pathways and gene expression.
Advantages of small-molecule inhibitors: Small-molecule inhibitors open up excellent opportunities for researchers studying multiple aspects of cell biology, ranging from cell cycle control and mitosis to signaling pathways and gene expression, and from migration and wound healing to apoptosis and autophagy. Small-molecule inhibitors typically yield highly penetrant effects across whole cell populations. In technical terms, using inhibitors is relatively straightforward, and they can easily be combined with other treatments. Inhibitors can often rapidly inactivate their targets, allowing experiments to be done with precise temporal control. In the case of enzymes such as protein kinases, inhibition with small molecules may still allow the enzyme to act as a scaffold for protein-protein interactions. If a small molecule is reversible, it may allow its target to be first inhabited and then reactivated. Small-molecule approaches can easily be applied to different cell lines.
Speaking of new drug research and development, small molecule inhibitors have many advantages compared with cytotoxic drugs, so they become an important tool for people to deeply understand the cell microenvironment and signal transduction pathways. They also provide hope for patients to obtain better clinical efficacy. At present, the indication for small molecule inhibitors tends to be cancer, but there has been increasing interest in their use for non-oncologic diseases as well, such as infectious diseases, inflammatory diseases, neurological diseases, and autoimmune diseases. In addition, there is an exciting prospect for small-molecule inhibitors to be used in combination with genome sequencing to develop personalized medicine. However, the current small-molecule inhibitor application is just the tip of an iceberg that is still unimaginable.

Classification of Small Molecule Inhibitors:
According to different signal pathways, bioactive small molecular compounds can be divided into: Angiogenesis, Apoptosis, Cell Cycle/Checkpoint, Metabolism/Endocrine/Hormone, Cytoskeletal Signaling, and GPCR/G Protein, etc.
--Angiogenesis: Angiogenesis is the process by which new capillary blood vessels form from pre-existing ones. Under physiological conditions, angiogenesis depends on the balance of positive and negative angiogenic modulators within the vascular microenvironment and requires the functional activities of several molecules, including angiogenic factors, extracellular matrix proteins, adhesion receptors, and proteolytic enzymes.
--Apoptosis: Apoptosis, in biology, is a mechanism that allows cells to self-destruct when stimulated by the appropriate trigger. Apoptosis can be triggered by mild cellular injury and by various factors internal or external to the cell; the damaged cells are then disposed of in an orderly fashion. Bioactive small molecular compounds that modulate apoptosis can either promote cell death or prevent it, depending on the therapeutic goal.
--Cell Cycle/Checkpoint: The cell cycle, is the ordered sequence of events that occur in a cell in preparation for cell division. The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions. Bioactive small molecular compounds that target the cell cycle and checkpoint mechanisms can either promote cell cycle arrest or induce cell death, making them valuable tools in cancer therapy.
--Cytoskeletal Signaling: The cytoskeleton is a dynamic network of proteins that provides structural support and regulates cellular processes such as migration, division, and signaling. Bioactive small molecular compounds that target cytoskeletal signaling pathways can modulate cell morphology, motility, and adhesion. The influence of cytoskeletal structures on signaling in vivo is often detected by the effects of specific agents, such as cytochalasin, colchicine, or acrylamide.
--Metabolism/Endocrine/Hormone: Metabolism, is the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material. Bioactive small molecular compounds that interact with metabolic pathways or modulate endocrine system function have the potential to treat conditions such as diabetes, obesity, and hormonal disorders.
--GPCR/G Protein: GPCRs are the largest family of membrane proteins and mediate most cellular responses to hormones and neurotransmitters, as well as being responsible for vision, olfaction and taste. GPCRs can act as agonists, antagonists, or allosteric modulators, influencing downstream signaling pathways. These compounds have wide-ranging therapeutic applications, including cardiovascular, neurological, and metabolic disorders.
