Megalomicin is a Micromonospora-produced macrolide antibiotic complex. Megalomicin A component was studied most extensively. It inhibited the ATP-dependent acidification of lysosomes and intra-Golgi transport in vitro. Megalomicin induces a powerful inhibitory effect on HIV-1 replication at nontoxic concentrations by preventing the processing of HIV-1 gp160 envelope protein and the subsequent formation of infectious viral particles.

Methyldihydromorphine is a synthetic narcotic analgesic related to the morphine. This compound has no pharmaceutical value in the US.

Avermectin B1a (AVM B1a), a widely used insecticide and acaricide, is reported to both activate and inhibit gamma-aminobutyric acidA (GABA(A)) receptor function in mammalian brain. Avermectin B1a is an antiparasitic agent that paralyzes nematodes without causing hypercontraction or flaccid paralysis. AVM B1a binds to two different sites in the GABA-gated chloride channel with dual effects, i.e., activating the channel on binding to the high-affinity site and blocking it on further binding to the low-affinity site.

Algestone is a progesterone like female hormone. Algestone is a C21-steroid that is pregn-4-ene substituted by oxo groups at position 3 and 20 and hydroxy groups at positions 16 and 17. It has a role as a progestin. It is a 20-oxo steroid, a 16alpha-hydroxy steroid, a 17-hydroxy steroid, a C21-steroid, a 3-oxo-Delta(4) steroid and a tertiary alpha-hydroxy ketone. It derives from a hydride of a pregnane. Algestone is used as anti-inflammatory drug (topical) and combination with enanthate as injectable contraceptive.

Daledalin is a norepinephrine reuptake inhibitor, developed in the 1970s by Pfizer. In animal models, daledalin potentiates the action of catecholamines, reverses the hypothermia induced by noradrenaline or noradnamine injected into the cerebral ventricles of mice. Daledalin potentiates amphetamine-induced excitation in rats and antagonizes reserpine-hypothermia in mice, tetrabenazine-sedation in rats and reserpine- and tetrabenazine-induced ptosis in mice. It inhibits noradrenaline and 5-hydroxytryptamine uptake by rat brain slices in vitro. In a clinical trial on patients with a depressive illness, no difference in efficacy between daledalin and amitriptyline was found.

ITAZIGREL, a thiazole derivative, is a potent platelet aggregation inhibitor.

Cabiotraxetan is a therapeutic carrier for radiolabel Yttrium, that can be used as diagnostic agent.

Devazepide (L-364718 or MK-329) is a nonpeptide antagonist for the peripheral (type-A) cholecystokinin (CCK) receptor, which has proved effective in blocking the actions of both exogenous and endogenous CCK in several species. It is an orally active antagonist of CCK-stimulated pancreaticobiliary output in man. Devazepide has been developing for the treatment of anxiety, cancer, neuropathic pain however development discontinued.

Cisconazole is a topical antifungal drug developed by Schering Corporation.
