4-Oxalocrotonate tautomerase (EC 5.3.2.-4-OT) is an enzyme that converts 2-hydroxymuconate to the αβ-unsaturated ketone, 2-oxo-3-hexenedioate. This enzyme forms part of a bacterial metabolic pathway that oxidatively catabolizes toluene, o-xylene, 3-ethyltoluene, and 1,2,4-trimethylbenzene into intermediates of the citric acid cycle. With a monomer size of just 62 amino acid residues, the 4-Oxalocrotonate tautomerase is one of the smallest enzyme subunits known. However, in solution, the enzyme forms a hexamer of six identical subunits, so the active site may be formed by amino acid residues from several subunits. This enzyme is also unusual in that it uses a proline residue at the amino terminus as an active site residue.

4-Methylpregabalin is a drug developed by Pfizer and related to pregabalin, which similarly acts as an analgesic with effectiveness against difficult to treat "atypical" pain syndromes such as neuropathic pain. The effectiveness of pregabalin and its older relative gabapentin against pain syndromes of this kind (which tend to respond poorly to other analgesic drugs) has led to their widespread use, and these drugs have subsequently been found to be useful for many other medical applications, including as anticonvulsants, muscle relaxants, anxiolytics and mood stabilisers.However these drugs are still of relatively low potency, and scientists have struggled for years to come up with an improvement on pregabalin, with increasing pressure to find a suitably improved replacement before the patent on pregabalin expires in 2018. While it was determined that the mechanism of action involves modulation of the α2δ calcium channel subunits (1 and 2), derivatives that appeared to be more potent and effective than pregabalin at this target when tested in vitro, repeatedly turned out to be weak or inactive when tested in animals. Eventually it was discovered that pregabalin is actively transported across the blood–brain barrier by the system L neutral amino acid transporter protein, which usually functions to transport certain amino acids, including leucine, valine and isoleucine, into the brain.This explained the previous failures, as most alterations to the pregabalin molecule which increase affinity for the α2δ channels and therefore increase apparent potency in the test tube, were found to also dramatically reduce binding to the system L transporter, and with no assisted transport into the brain, blood–brain barrier penetration was minimal and the drugs were inactive in animals. However, after extensive searching it was discovered that one enantiomer of the relatively simple derivative 4-methylpregabalin, was both 4x higher in binding affinity to α2δ channels than pregabalin, and also retained similar affinity for the system L transporter. This was tested in animals and as hoped, was found to have similar effectiveness to pregabalin as an analgesic and with around 2-3x the potency.It remains unclear at this stage whether (3R,4R)-4-methylpregabalin will now be further developed for medical use in humans however, given the recent development of several competing drugs from the same family which are much further advanced in clinical trials.

4-Phenylfentanyl is an opioid analgesic that is a derivative of fentanyl. It was developed during the course of research that ultimately resulted in super-potent opioid derivatives such as carfentanil, though it is a substantially less potent analogue. 4-Phenylfentanyl is around 8x the potency of fentanyl in analgesic tests on animals, but more complex 4-heteroaryl derivatives such as substituted thiophenes and thiazoles are more potent still, as they are closer bioisosteres to the 4-carbomethoxy group of carfentanil.Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.

4-O-Methylhonokiol is a neolignan, a type of phenolic compounds. It is found in the bark of Magnolia grandiflora and in M. virginiana flowers.4-O-Methylhonokiol is a potent CB2 receptor ligand (Ki = 50 nM), showing a unique inverse agonism and partial agonism via different pathways (cAMP and Ca2+) and potently inhibits osteoclastogenesis. 4-O-Methylhonokiol further attenuates memory impairment in presenilin 2 mutant mice through reduction of oxidative damage and inactivation of astrocytes and the ERK pathway. The different neuroprotective and anti-Alzheimer Disease effects reported in rodent models may be mediated via CB2 receptors, providing that the compound should be orally bioavailable to the brain. It was shown that 4-O-methylhonokiol activates CB2 receptors and also inhibits the oxygenation of the major endocannabinoid 2-AG via COX-2 in a substrate-selective manner, thus leading to potential synergistic effects at CB receptors. The same study also provided data that this natural product can readily pass the blood–brain barrier, using LC-MS/MS.

In enzymology, a 4-alpha-glucanotransferase (EC 2.4.1.25) is an enzyme that catalyzes a chemical reaction that transfers a segment of a 1,4-alpha-D-glucan to a new position in an acceptor carbohydrate, which may be glucose or a 1,4-alpha-D-glucan.This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 1,4-alpha-D-glucan:1,4-alpha-D-glucan 4-alpha-D-glycosyltransferase. Other names in common use include disproportionating enzyme, dextrin glycosyltransferase, D-enzyme, debranching enzyme maltodextrin glycosyltransferase, amylomaltase, and dextrin transglycosylase. This enzyme participates in starch and sucrose metabolism in plants. Studies of the enzyme from potato led to the discovery of cycloamylose.

threo-4-Methylmethylphenidate (4-MeTMP) is a stimulant drug related to methylphenidate. It is slightly less potent than methylphenidate and has relatively low efficacy at blocking dopamine reuptake despite its high binding affinity, which led to its investigation as a possible substitute drug for treatment of stimulant abuse (cf. nocaine). On the other hand, several other simple ring-substituted derivatives of threo-methylphenidate such as the 4-fluoro and 3-chloro compounds are more potent than methylphenidate both in efficacy as dopamine reuptake inhibitors and in animal drug discrimination assays.

4-NEMD is a potent sedative drug which acts as a selective alpha-2 adrenergic agonist. It is closely related to dexmedetomidine but is several times more potent. Like other alpha-2 agonists, it produces sedative and muscle relaxant effects but without producing respiratory depression. It is not currently used in medicine but has been researched as the basis for a potential new generation of alpha-2 agonist drugs, which may have selectivity for the different subtypes of the alpha-2 receptor.
